Siemens SINAMICS S120/S150 User Manual: An Operational Guide

The Siemens SINAMICS S120/S150 drive systems are widely used in industrial automation for controlling electric motors. In this guide, we will explore the various features and operations of these systems, covering aspects such as the operation panel, parameter copying, initialization, password settings, parameter access control, and external control connections.

Siemens CU320-2DP

1. Introduction to the Operation Panel (BOP20)

The Basic Operator Panel (BOP20) is an essential interface for the SINAMICS S120 system, offering six buttons and a backlit display for operation. It is designed for simple and efficient interaction with the system, enabling the user to input parameters, display runtime status, and manage errors.

Key Features of BOP20:

  • Control and Monitoring: It allows users to input parameters, monitor the system status, and reset faults.
  • Access Control: Through the BOP20, users can set the access level, where higher access allows modification of more parameters.
  • Error Handling: The panel displays alarms and errors, with options to acknowledge and reset them*2. Copying Parameters Between Drives**

Copying parameters from one drive to another is a common requirement when setting up multiple systems with the same configuration. This can be easily done using the BOP20 or through the expert parameter settings in the STARTER software.

To copy parameters from RAM to ROM:

  1. Press and hold the “P” button for three seconds, or
  2. Use parameters like p0009 = 0 and p0977 = 1 to initiate the copy .

This sures that all system parameters are consistent across devices and securely saved in non-volatile memory.

3. Parameter Initialization and Factory Reset

For initial setups or after a fault, it may be necessary to perform a full initialization or a factory reset. This can be done either by using the BOP20 or directly through software tools.

To reset the system:

  1. Set parameter p0009 = 30 to perform a factory reset.
  2. Ensure all components return to their default settings.

This procedure is essential for clearing incorrect configurations or preparing a device for deployment in a different setup.

4. Password Management

To protect the drive system’s settings from unauthorized changes, the S120 allows the user to set a password for configuration access. Passwords can be configured and removed using parameters in the system.

  • Setting a Password: Input the desired password through parameter settings in the expert parameter list.
  • Removing a Password: The password can be cleared by setting specific parameters (e.g., p9761 = 0) .

*5. Par

Access control is crucial for preventing unauthorized changes to system parameters. The S120 system allows for different levels of access, controlled via the BOP20 or the parameter configuration menu. By adjusting the parameter p0003, users can restrict access to certain critical parameters, ensuring that only qualified personnel can modify essential settings .

6. External Control: Forwarrse Rotation, Speed Control via Potentiometer

The SINAMICS S120 offers flexible options for integrating external devices, such as external switches and potentiometers, to control motor operations.

  • Forward and Reverse Rotation: You can connect external terminals to control the motor’s direction. Specific parameters (P2589 and P2590) are used to define the command source for forward and reverse motion .
  • Speed Control: For adjusting motor speexternal potentiometer, parameters such as P2585 and P2586 can be set to receive and process the analog signals from the potentiometer .

This flexibility ensures that the S120 can be tailorde range of industrial applications, offering both manual and automated control options.

7. Common Fault Codes and Troubleshooting

The S120 system is equipped with an extensive set of diagnostic tools to identify and address issues quickly. Some common fault codes include:

  • F01650/F30650: This fault is triggered when the CRC check for Safety Integrated (SI) parameters fails .
  • F01680/F30680: This indicates discrepancies in the safettion during operation .

To troubleshoot, ensure that parameters related to Safety Integrated ary configured and that any changes to the system are properly validated through the STARTER or BOP20 interface .

8. Conclusion

The SINAMICS S120 and S150 drives offer advanced feature control, with a user-friendly interface, flexible configuration options, and robust safety and diagnostic features. By understanding the operation panel, copying parameters, initializing settings, and configuring passwords and external control systems, users can ensure optimal performance and secure operation of their industrial automation systems. Additionally, being aware of the fault codes and how to address them will help maintain the system’s reliability and efficiency.

For more advanced configurations and troubleshooting, refer to the SINAMICS S120 Parameter Manual and the related documentation to fully leverage the capabilities of these systems.

This guide incorporates the essential features of the SINAMICS S120 and S150 systems, as outlined in the manuals provided, and addresses user concerns regarding setup, security, control, and fault management.

Methods for Unlocking Hidden Parameters and Modifying Mainboard Power of ABB ACS800 Series Inverters

The ABB ACS800 series inverters are high-performance inverters widely used in industrial control. To meet the needs of different application scenarios, users sometimes need to adjust the power of the inverter or unlock hidden parameters. The following will detail the methods for unlocking hidden parameters and modifying the mainboard power of the ACS800 series inverters.

Method for Unlocking Hidden Parameters

In the ACS800 series inverters, some parameters are hidden and can only be accessed by following specific steps. Here are the steps to unlock hidden parameters:

  1. Enter the parameter setting interface: First, enter the parameter setting interface of the inverter.
  2. Set the unlock code: Set parameter 16.03 (PASS CODE) to 358. This operation will unlock the hidden parameter groups and make them visible.
  3. Access hidden parameters: After unlocking, you can access hidden parameter groups such as group 112 and group 190.

By following these steps, users can access and modify parameters that are usually invisible for more advanced settings and adjustments.

Method for Modifying Mainboard Power

In some cases, users may need to adjust the power of the ACS800 inverter. The following are the steps for modifying the power of RDCU boards with different versions:

For RDCU Boards with Version Numbers Before 7200

  1. Enter parameter 9903 and change it to YES.
  2. Enter parameter 1603 and change it to 564.
  3. Enter parameter 11206 and select XXNONE.
  4. Power off and then on again.
  5. Re-enter parameter 1603 and change it to 564.
  6. Enter parameter 11206 and select the desired power (e.g., 170-3).
  7. Initialize the parameters.
  8. Power off and then on again.

For RDCU Boards with Version Numbers 7200 and Later

  1. Enter parameter 9903 and change it to YES.
  2. Enter parameter 1603 and change it to 564.
  3. Enter parameter 11221 and select the desired power (e.g., 170-3).
  4. Re-enter parameter 9903 and change it to YES.
  5. Power off and then on again.

Notes:

  • Parameters 11219 to 11223 correspond to different power levels. Be cautious when modifying them to select the correct parameters.
  • For inverters in normal use, do not operate or modify parameters arbitrarily to avoid losing normal parameters.
  • Using parameter 2303 can open single drive groups from 100 to 202.

Steps for Changing Inverter Type

In addition to changing the power, sometimes it is also necessary to change the type of inverter. Here are the steps for changing the inverter type:

  1. Set parameter 16.03 (PASS CODE) to 564 to make parameter groups 112 and 190 visible.
  2. Select the desired inverter type from parameter groups 112.20 to 112.36. For example, for an ACS800-01-0016-3 machine, select 11.21 = sr0016_3.
  3. The panel will prompt to power off. Power off the RMIO board and then on again.

Conclusion

By following these methods, users can unlock the hidden parameters of the ABB ACS800 series inverters and adjust the mainboard power and inverter type as needed. These operations can help users better adapt to different application scenarios and improve the flexibility and performance of the equipment. However, when performing these operations, be cautious and ensure that the correct parameters are selected to avoid affecting the normal operation of the equipment.
