The TECO JSDAP series servo drive is a high-performance servo system widely applied in various industrial automation scenarios. To facilitate better operation and maintenance of the JSDAP series servo drive, this article will provide a detailed introduction to its status display and diagnostic functions, trial operation of the servo motor without load in conjunction with an upper-level controller, parameter reset, fan operation settings, position mode control, electronic gear ratio settings, and fault code analysis.

I. Status Display and Diagnostic Functions

Status Display Function

The status display function of the JSDAP servo drive is realized through the LED seven-segment display and LED lights on the panel. When the drive is powered on, the POWER indicator light on the panel illuminates, indicating that the drive is properly powered. The CHARGE indicator light remains lit until the main circuit is completely discharged after the power is turned off, reminding users not to touch the circuit or replace components at this time. Users can cycle through various parameters, including status display parameters, diagnostic parameters, abnormal alarm records, system parameters, torque control parameters, speed control parameters, and position control parameters, by pressing the MODE key.

Diagnostic Function

The diagnostic function allows users to view various information about the current system, such as the current control mode (dn-01), output contact signal status (dn-02), input contact signal status (dn-03), CPU software version (dn-04), etc. This diagnostic information is extremely helpful for troubleshooting and system debugging.

II. Trial Operation of Servo Motor Without Load in Conjunction with an Upper-Level Controller

Trial operation of the servo motor without load is an important step to verify the correctness of the drive configuration and wiring. Before trial operation, it is necessary to ensure that the drive power supply, motor wiring, and encoder wiring are all correct. During trial operation, the JOG function on the drive panel can be utilized to check the motor’s operating speed and direction.

Specific steps are as follows:

1. Fix the servo motor onto the machine platform to prevent it from jumping or moving during trial operation.
2. Check whether the drive power supply, motor wiring, and encoder wiring are correct. Remove the control signal wires (CN1).
3. Turn on the drive power. If an abnormality is displayed on the panel, troubleshoot according to the abnormality code.
4. Release the mechanical brake (if the motor is equipped with one).
5. Use the panel to operate the JOG function and check whether the motor’s operating speed and direction are correct. If abnormalities are found, adjust the speed control parameters (such as Sn201) and system parameters (such as Cn004).

III. Parameter Reset and Fan Operation Settings

Parameter Reset

If a parameter reset is required for the drive, it can be achieved by simultaneously pressing the UP and DOWN keys on the panel. After resolving the abnormal alarm, first deactivate the input contact SON (i.e., deactivate the motor excitation state), then simultaneously press the UP and DOWN keys. The panel will display “RESET” and immediately return to the parameter selection screen, indicating that the abnormal alarm has been correctly cleared.

Fan Operation Settings

Fan operation settings are adjusted through relevant parameters. Specific setting methods are detailed in the relevant sections of the user manual. Generally, control parameters can be adjusted to set the fan’s start-up temperature and operation mode to ensure the drive operates at an appropriate temperature.

IV. Position Mode Control and Electronic Gear Ratio Settings

Position Mode Control

Position mode control is suitable for applications requiring precise control of the motor’s position. In position mode, the motor’s position is controlled by external pulse command signals. To achieve position mode control, correct wiring and parameter settings are required.

In terms of wiring, the pulse command signals (Pulse and /Pulse) and signal signs (Sign and /Sign) need to be connected to the corresponding contacts of the CN1 control signal terminal. Simultaneously, ensure that the drive power supply, motor wiring, and encoder wiring are all correct.

For parameter settings, the control mode selection parameter (Cn001) needs to be set to position control mode (usually 2 or 3), and the electronic gear ratio parameters (Pn302~Pn306) need to be set to adapt to different application requirements. The electronic gear ratio is used to convert pulse command signals into the motor’s actual movement distance.

Electronic Gear Ratio Settings

The setting of the electronic gear ratio is crucial for the accuracy of position control. By adjusting the electronic gear ratio parameters (Pn302~Pn306), the proportional relationship between the pulse command signal and the motor’s actual movement distance can be changed. Specific setting methods are detailed in the relevant sections of the user manual. Generally, the appropriate electronic gear ratio needs to be calculated and set based on the motor encoder’s specifications and the machine platform’s application specifications.

V. Fault Code Meaning Analysis and Troubleshooting

During operation, the JSDAP servo drive may display various fault codes. These codes typically indicate specific abnormal types, such as overvoltage, overcurrent, encoder abnormalities, etc. When a fault code appears, users should first consult the fault code table in the user manual to understand the abnormal type and its possible causes.

Troubleshooting methods usually include checking whether the wiring is correct, whether the parameter settings are reasonable, whether the external load is too heavy, etc. After resolving the fault, utilize the abnormal reset function on the drive panel to clear the abnormal alarm and restore the drive’s normal operation.

VI. Conclusion

This article provides a detailed introduction to the operation guide for the TECO JSDAP series servo drive user manual, covering status display and diagnostic functions, trial operation of the servo motor without load in conjunction with an upper-level controller, parameter reset, fan operation settings, position mode control, electronic gear ratio settings, and fault code analysis. By following the guidance in this article, users can better operate and maintain the JSDAP series servo drive, ensuring its stable and reliable operation in various industrial automation scenarios.

I. Introduction to the Operation Panel Functions and Settings for Passwords and Parameter Locks

The TECO A510S series frequency converter’s operation panel serves as its core control interface, offering intuitive operation and monitoring functions. Equipped with an LED display, multiple function keys, and status indicators, users can easily set parameters, monitor operating status, and troubleshoot faults.

Setting and Clearing Passwords:
To protect parameter settings from unauthorized changes, the A510S series provides a password protection feature. To set a password, users need to enter the “Maintenance Function Group” (parameter group 13) and set the “Parameter Password Function” (parameter 13-07) to a value between 0 and 65534. To clear the password, simply reset this parameter to 0.

Parameter Locking and Unlocking:
The parameter lock function prevents unauthorized users from modifying converter parameters. By setting “Parameter Lock” (parameter 13-06) to 1, users can restrict modifications to only preset “User Parameters” (parameters 00-41 to 00-56). To unlock all parameters, set this parameter to 2.

Setting Monitor Status to Current and Actual Frequency:
To monitor the converter’s current and actual output frequency in real-time, users need to enter the “Monitor Function Group” (parameter group 12) and adjust the “Display Screen Selection” (parameter 12-00) to set the LED display’s content. For example, setting the highest bit to 1 (output current) and the lowest bit to 2 (output voltage) will display both current and voltage on the panel. Similarly, by adjusting other bits of parameter 12-00, users can select other monitoring parameters like actual frequency.

II. Terminal Forward/Reverse Control and External Potentiometer Speed Regulation

The TECO A510S series supports forward/reverse control and speed regulation via external terminals. Specific wiring and parameter settings are as follows:

Forward/Reverse Control:
To achieve forward/reverse control, users need to connect the multi-function digital input terminals (e.g., S1 and S2) of the converter to external control signal sources. In the parameter settings, set “Multi-function Terminal S1 Function Setting” (parameter 03-00) to 0 (forward/stop command) and “Multi-function Terminal S2 Function Setting” (parameter 03-01) to 1 (reverse/stop command). This way, when terminal S1 receives a high-level signal, the converter will rotate forward; when terminal S2 receives a high-level signal, it will rotate reverse.

External Potentiometer Speed Regulation:
External potentiometer speed regulation dynamically adjusts the converter’s output frequency via an analog signal (e.g., 0-10V or 4-20mA). Users need to connect the output end of the potentiometer to the converter’s analog input terminal (e.g., AI1 or AI2) and enable the corresponding analog input function in the parameter settings. For example, set the “AI1 Signal Scan Filter Time” (parameter 04-01) to an appropriate value to eliminate signal interference and set “AI1 Function Setting” (parameter 04-00) to 0 (0-10V input). Then, adjusting the potentiometer will change the converter’s output frequency.

III. Fault Code Meaning Analysis and Solutions

When a fault occurs in the TECO A510S series converter, it will display the corresponding error code, helping users quickly locate the problem. Below are some common fault code meanings and solutions:

• OC (Overcurrent): Indicates that the converter’s output current exceeds the rated value. Possible causes include motor overload, output short circuit, etc. Solutions include checking the motor load and examining the output circuit for shorts.
• OL1 (Motor Overload): Indicates motor overload. Possible causes include excessive load, too short acceleration time setting, etc. Solutions include reducing the load and increasing the acceleration time.
• OH1 (Heat Sink Overheat): Indicates inadequate converter cooling. Possible causes include high ambient temperature, faulty cooling fan, etc. Solutions include improving cooling conditions and replacing the cooling fan.
• UV (Undervoltage): Indicates that the input voltage is below the rated value. Possible causes include unstable power supply voltage and poor input circuit contact. Solutions include checking the power supply voltage and examining the input circuit connections.

IV. Conclusion

The TECO A510S series frequency converter user manual provides detailed operation guides and parameter setting instructions, helping users easily get started and efficiently operate and maintain the converter. Through this guide, users can learn how to operate the panel, set passwords and parameter locks, achieve terminal forward/reverse control and external potentiometer speed regulation, as well as interpret and solve common fault codes. The realization of these functions and application scenarios relies heavily on a thorough understanding and correct application of the user manual. Therefore, it is recommended that users carefully read the user manual before operating the converter and strictly follow the instructions for operation and settings.

The WELLER S320 Inverter, as a powerful variable frequency speed control device, is widely used in various industrial control systems. To ensure its correct and efficient operation, this article will provide a detailed operation guide for the WELLER S320 Inverter, covering four main aspects: sensor selection and settings, external start mode and return water control settings, relay output function settings, and fault code analysis and troubleshooting.

I. Sensor Selection and Settings

As the “eyes” of the inverter, the type and range of the sensor directly affect the system’s accuracy and stability. The WELLER S320 Inverter supports both voltage and current sensors. When choosing the sensor type, it is necessary to consider the actual application scenario and system requirements. Voltage sensors are suitable for situations requiring high signal stability, while current sensors are more suitable for long-distance transmission or environments with high interference.

Setting the sensor range is equally important. The WELLER S320 Inverter offers three ranges: 0.0-10.0 bar, 0.0-16.0 bar, and 0.0-25.0 bar. During setting, it is essential to select a range that reasonably covers the system’s operating pressure to ensure the sensor can accurately reflect the system status.

Pressure calibration is a crucial step to ensure the accuracy of the inverter. By adjusting parameter E0.04, the sensor can be calibrated. During the calibration process, ensure the system is in a stable state to avoid external interference affecting the calibration results.

Parameters related to pressure deviation include wake-up pressure deviation (E0.05) and high-pressure alarm deviation (E0.06). The wake-up pressure deviation sets the pressure threshold for the inverter to wake up, while the high-pressure alarm deviation sets the threshold for the high-pressure alarm. Properly setting these two parameters can effectively protect the system from excessive or too low pressure.

The PID sleep and wake-up functions are important means to improve system energy efficiency. By setting parameter E2.07 to 1, the PID sleep function can be enabled. At the same time, by adjusting parameters E2.08 and E2.09, the PID wake-up delay and sleep deviation pressure can be set to meet the needs of different systems.

The water shortage protection function is essential for protecting pumps and preventing system damage. By setting parameter E0.19 to 1 or 2, the water shortage protection function can be enabled. It is also necessary to reasonably set parameters such as E0.20 (water shortage fault detection threshold), E0.21 (water shortage protection frequency), and E0.22 (water shortage protection detection current percentage) to ensure that the water shortage protection function can accurately and timely respond to changes in the system status.

II. External Start Mode and Return Water Control Settings

Setting the inverter to external start mode allows convenient control of the inverter’s start and stop through external signals. By setting parameter E0.08 to 1 and selecting the appropriate DI function (e.g., setting E0.29 to 1), the external start function can be achieved. Simultaneously, by adjusting parameter E0.28, the power-on self-start delay time can be set to meet the start-up requirements of different systems.

Return water control is an important application of the inverter in heating, water supply, and other fields. By setting parameter E5.06 to 1 or 2, the return water control mode can be enabled. It is also necessary to reasonably set parameters such as E5.00 (return water temperature set value), E5.01 (return water shut-off temperature offset), E5.02 (maximum operating time of return water control), and E5.03 (allowable time interval for return water control operation) to ensure the stable operation of the return water control system and meet actual needs.

The relay output function is a crucial means to realize the联动 control between the inverter and other devices. By setting parameter E0.34, different relay output functions can be selected, such as forward operation, reverse operation, fault output, etc. Simultaneously, by adjusting parameters E0.35 and E0.36, the relay closing and opening delay times can be set to meet the control requirements of different systems.

III. Fault Code Analysis and Troubleshooting

The WELLER S320 Inverter features rich fault code prompts, helping users quickly locate and resolve issues. For example, when the inverter encounters an E004 acceleration overcurrent fault, possible causes include too fast acceleration, low grid voltage, or insufficient inverter power. To address such faults, methods such as increasing the acceleration time, checking the input power supply, or selecting an inverter with a larger power rating can be employed.

Similarly, when the inverter experiences an E026 water shortage fault, possible causes include municipal water pipe network shortage, pump failure, or sensor failure. To address such faults, one can check whether parameters E0.19, E0.20, E0.21, and E0.22 are set correctly or seek help from professional service personnel.

IV. Conclusion

The WELLER S320 Inverter, as a powerful and flexible variable frequency speed control device, plays an important role in various industrial control systems. By reasonably selecting sensor types and ranges, calibrating pressure, setting pressure deviation-related parameters, and configuring the PID sleep and wake-up functions, the inverter can accurately reflect the system status and operate stably. Additionally, through external start mode and return water control settings, as well as relay output function configurations, the inverter can realize联动 control with other devices and meet the needs of different systems. Furthermore, familiarity with the meaning and solutions of the inverter’s fault codes is also essential for ensuring the stable operation of the system.

In practical applications, users should perform personalized settings and adjustments to the inverter based on specific requirements and regularly maintain and inspect the inverter to ensure its long-term stable operation. Simultaneously, when encountering problems, users should promptly seek help from professional service personnel to ensure timely and effective solutions.
