This document aims to provide users with a comprehensive operational guide, covering aspects such as the operation panel functions, parameter settings, external control, and fault handling, to assist users in efficiently utilizing and maintaining this inverter.
II. Detailed Explanation of Operation Panel Functions
(I) Basic Functions of the Operation Panel
The operation panel of the FST-650 Series inverter is intuitively designed and comprehensive in functionality, including:
- Program Key: Used to enter or exit menus.
- Confirm Key: Navigates through menus step-by-step, sets, and confirms parameters.
- Up/Down Keys: Adjust data and function codes.
- Right Shift Key: Shifts right to select parameters when the inverter is stopped or in the operation interface; selects the digit to modify when changing parameters.
- Run Key: Starts the inverter in keyboard operation mode.
- Stop/Reset Key: Stops the operation in the running state; resets the inverter during a fault alarm.
(II) Restoring Factory Parameter Settings
- Enter the parameter setting interface and locate F0.00.
- Set F0.00 to the default value (usually 0).
- Confirm the setting, and the inverter will restore to factory default settings.
(III) Password Setting and Removal
- Enter the parameter setting interface and find FP.00.
- Enter a new password and confirm.
- To remove the password, set FP.00 to the default value (usually 0).
(IV) Parameter Access Restriction
- Enter the parameter setting interface and locate FP.01.
- Set the parameter access restriction level and confirm.
- Users with different levels will have different access and modification permissions for parameters.
III. External Terminal Control and Potentiometer Speed Regulation
(I) External Terminal Forward/Reverse Control
- Terminal Connections: X1 (Forward Run FWD), X2 (Reverse Run REV).
- Parameter Settings:
- Enter the parameter setting interface and find F4.00 and F4.01.
- Set F4.00 to 1 (Forward) and F4.01 to 2 (Reverse).
- Confirm the settings, and the inverter will control forward/reverse based on the external terminal status.
(II) External Potentiometer Speed Regulation
- Terminal Connections: AI1 (Analog Input Terminal, connected to the potentiometer).
- Parameter Settings:
- Enter the parameter setting interface and find F0.03.
- Set F0.03 to 2 (Analog VCI Setting).
- Confirm the setting, and the inverter will regulate speed based on the potentiometer input signal.
IV. Fault Codes and Handling Methods
(I) Common Fault Codes
- Err01: Overcurrent Fault
- Err02: Overvoltage Fault
- Err03: Undervoltage Fault
- Err04: Overheat Fault
- Err05: Phase Sequence Fault
- Err06: Ground Fault
(II) Fault Handling Methods
- Err01: Check the load and cable connections to ensure the load is within the allowable range.
- Err02: Check the input voltage and cable connections to ensure the voltage is within the allowable range.
- Err03: Check the input voltage and cable connections to ensure the voltage does not fall below the set value.
- Err04: Check the inverter’s cooling conditions to ensure proper ventilation and that the heat sink is functioning correctly.
- Err05: Check the input power phase sequence and cable connections to ensure the phase sequence is correct.
- Err06: Check the ground connection and cable connections to ensure the ground is properly connected.
