1. Introduction to the Inverter Control Panel
1.1 Control Panel Layout and Button Functions
The Lingshida LSD-A1000 series inverter control panel integrates a display screen and multiple functional buttons, facilitating parameter settings, status monitoring, and fault troubleshooting. The panel layout is as follows:
| Button/Indicator | Function Description |
|---|---|
| RUN (Run) | Starts the inverter operation |
| STOP/RST (Stop/Reset) | Stops operation or resets faults |
| PRG/ESC (Program/Exit) | Enters or exits parameter setting mode |
| DATA/ENT (Data/Enter) | Confirms parameter settings or enters the next menu level |
| △ (Increase) | Increases parameter values or selects the previous item |
| ▽ (Decrease) | Decreases parameter values or selects the next item |
| →/SHIFT (Shift) | Switches display parameters or selects the modification position |
| QUICK/JOG (Quick/Jog) | Quick function switching or jog operation |
| Potentiometer Knob | Adjusts output frequency or other analog parameters |
| LED Indicators | Displays operating status, fault status, frequency, current, voltage, etc. |
LED Indicator Descriptions:
- RUN (Red): Inverter is running.
- FWD/REV (Red): Motor is in forward/reverse operation.
- LOCAL/REMOT (Red): Local/remote control mode.
- TC (Red): Torque control mode or fault status (flashing indicates a fault).
1.2 How to Restore Factory Default Settings
The Lingshida LSD-A1000 series inverter supports restoring all parameters to factory default values. Follow these steps:
- Enter Parameter Setting Mode:
- Press the PRG/ESC key to enter the function code editing state.
- Use the △/▽ keys to select FA-11 (Product Number) or FA-12 (Software Version Number) to confirm the current version.
- Restore Factory Settings:
- In the stopped state, press and hold the PRG/ESC key for more than 5 seconds until the display shows the “rES” prompt.
- Press the DATA/ENT key to confirm the restoration of factory settings.
- The inverter will restart, and all parameters will be reset to default values.
Note:
- Restoring factory settings will clear all user-defined parameters, including passwords and PID parameters.
- After restoration, you need to reconfigure motor parameters (such as rated current and rated frequency).
1.3 How to Set and Remove Passwords
To prevent unauthorized parameter modifications, the Lingshida LSD-A1000 supports password protection.
Setting a Password:
- Enter FA-00 (User Password Setting):
- Press PRG/ESC → Select the FA group → Select FA-00.
- Enter a 5-digit password (default is 00000).
- Press DATA/ENT to confirm.
- Enable Password Protection:
- Enter FA-01 (Password Protection Enable):
- 0: Disable password protection.
- 1: Enable password protection.
- Enter FA-01 (Password Protection Enable):
Removing a Password:
- Enter the Correct Password:
- When entering parameter settings, the system prompts for a password.
- Enter the correct password and press DATA/ENT to confirm.
- Reset Password if Forgotten:
- Press and hold the PRG/ESC key for 5 seconds to restore factory settings (password resets to 00000).
Note:
- After setting a password, modifying critical parameters (such as F3 group motor parameters) requires entering the password.
- The manufacturer’s password (for advanced parameters) cannot be cleared by restoring factory settings; contact the manufacturer.
1.4 How to Set Parameter Access Restrictions
To prevent accidental modifications, you can restrict access to certain parameters:
- Set Parameter Modification Permissions:
- The “Change” column in the function code table indicates modification permissions:
- ★: Can be modified during both operation and stop.
- ☆: Can only be modified when stopped.
- ●: Read-only, cannot be modified (such as fault records).
- The “Change” column in the function code table indicates modification permissions:
- Lock Critical Parameters:
- After setting a password in FA-00 (User Password), parameters in F3 group (Motor Parameters) and FC group (PID Parameters) cannot be modified without the password.
- Lock Buttons:
- Set via FA-00 (QUICK/JOG Key Function):
- 0: QUICK/JOG key is disabled.
- 1: Switch between local and remote control.
- 2-4: Jog function (to prevent accidental operation).
- Set via FA-00 (QUICK/JOG Key Function):
2. Terminal Forward/Reverse Control and External Potentiometer Frequency Adjustment
2.1 Parameter Settings and Wiring for Terminal Forward/Reverse Control
The Lingshida LSD-A1000 supports forward/reverse control through DI (Digital Input) terminals.
Parameter Settings:
| Function Code | Setting Value | Description |
|---|---|---|
| F6-00 (DI1 Function Selection) | 1 (Forward Run) | DI1 connected for forward operation |
| F6-01 (DI2 Function Selection) | 2 (Reverse Run) | DI2 connected for reverse operation |
| F6-11 (Terminal Command Mode) | 0 (Two-Wire Mode 1) | DI1/DI2 control forward/reverse separately |
Wiring Steps:
- Connect DI1 (Forward) and DI2 (Reverse):
- Connect DI1 to the forward button or PLC output.
- Connect DI2 to the reverse button or PLC output.
- Connect COM to 24V- (common ground).
- Set Command Source:
- F0-21 (Command Source Selection) = 1 (Terminal Command Channel).
- Start Testing:
- Connect DI1, and the motor runs forward.
- Connect DI2, and the motor runs in reverse.
Note:
- Ensure F1-06 (Stop Mode) = 0 (Deceleration Stop) to avoid sudden stops.
- For three-wire control (forward/reverse/stop), set F6-11 = 2 (Three-Wire Mode 1).
2.2 Parameter Settings and Wiring for External Potentiometer Frequency Adjustment
Frequency adjustment can be achieved through AI1 (Analog Input) using an external potentiometer.
Parameter Settings:
| Function Code | Setting Value | Description |
|---|---|---|
| F0-02 (Main Frequency Source Selection) | 2 (AI1) | Frequency given by AI1 |
| F6-13 (AI Curve Minimum Input) | 0.00V | Potentiometer minimum voltage corresponds to 0Hz |
| F6-16 (AI Curve Maximum Input) | 10.00V | Potentiometer maximum voltage corresponds to 50Hz |
| J13 (AI1 Input Mode) | 1-2 (0-10V) | Voltage input mode |
Wiring Steps:
- Connect the Potentiometer:
- Connect the middle pin of the potentiometer to AI1.
- Connect one end of the potentiometer to +10V (provided by the inverter).
- Connect the other end of the potentiometer to COM.
- Set Frequency Range:
- F0-09 (Maximum Frequency) = 50.00Hz.
- F0-12 (Minimum Frequency) = 0.00Hz.
- Start Testing:
- Rotate the potentiometer, and the output frequency changes with the voltage.
Note:
- The potentiometer resistance is recommended to be 5K-10KΩ.
- For current input (4-20mA), short J13 to 2-3.

3.2 Fault Cause Analysis and Solutions
E02 (Acceleration Overcurrent)
- Cause: Acceleration time is too short, or the load inertia is too large.
- Solution:
- Increase F0-13 (Acceleration Time 1).
- Check if the motor is locked.
E05 (Acceleration Overvoltage)
- Cause: Input voltage is too high, or the braking unit is not enabled.
- Solution:
- Check if the input voltage is within 380V±10%.
- Enable F1-14 (Energy Consumption Braking Point) and connect a braking resistor.
E11 (Motor Overload)
- Cause: Motor overheating, cooling fan failure.
- Solution:
- Check if the motor cooling is normal.
- Adjust F8-01 (Motor Overload Protection Gain).
E12 (Input Phase Loss)
- Cause: Loose power line, blown fuse.
- Solution:
- Check if the R/S/T terminals are properly connected.
- Replace the fuse.
E16 (Communication Fault)
- Cause: MODBUS line disconnection, address conflict.
- Solution:
- Check the RS485 line connection.
- Ensure P0-01 (Communication Address) is unique.
4. Summary and Precautions
- Control Panel: Familiarize yourself with button functions and set passwords and parameter restrictions reasonably.
- Terminal Control: Correctly wire DI/AI terminals to avoid misoperation.
- Fault Troubleshooting: Check power supply, load, and parameter settings one by one according to fault codes.
