I. Control Panel Features

1. Control Panel Functions

The control panel of the Xilin EH600A series integrates rich functionalities, allowing users to modify parameters, monitor status, and control operations such as start, stop, and forward/reverse. The main functions include:

• Parameter Modification: Users can modify various functional parameters, such as frequency settings, motor parameters, and control modes.
• Status Monitoring: The control panel displays the operating status, including output frequency, current, and voltage.
• Operation Control: Users can control the start, stop, and forward/reverse operations of the inverter.

2. Parameter Copying and Initialization

Parameter Copying

To copy parameters from one inverter to another:

1. Use the dedicated communication software (e.g., the parameter setting software for EH600A) to export and save the parameters from the source inverter.
2. Connect the target inverter to the computer via a communication cable and open the software.
3. Import the saved parameters into the target inverter.
4. Restart the target inverter to apply the parameters.

Parameter Initialization

To reset the inverter parameters to factory settings:

1. Enter the parameter setting interface on the control panel.
2. Locate the FD parameter group and set FD.10 (Parameter Initialization) to 1 (Restore Factory Settings).
3. Save the parameters and restart the inverter to apply the factory settings.

3. Password Settings and Removal

Setting a Password

To prevent unauthorized access to parameter modifications:

1. Enter the parameter setting interface on the control panel.
2. Locate the F6 parameter group and set F6.08 (User Password) to a 4-digit number (e.g., 1234).
3. Save the parameters. The system will prompt for the password the next time you enter the parameter setting interface.

Removing the Password

To disable the password protection:

1. Enter the parameter setting interface using the current password.
2. Set F6.08 to 0 and save the parameters.
3. The password protection will be disabled.

4. Parameter Access Restrictions

To prevent unauthorized parameter modifications:

1. Enter the parameter setting interface on the control panel.
2. Locate the F6 parameter group and set F6.08 (User Password) to a non-zero value (e.g., 1234).
3. Save the parameters. The system will prompt for the password the next time you enter the parameter setting interface.

II. External Control Functions

1. External Terminal Forward/Reverse Control

The EH600A series supports forward/reverse control via external terminals. The following steps outline the wiring and parameter settings:

Wiring

• FWD (Forward): Connect to the forward control signal.
• REV (Reverse): Connect to the reverse control signal.
• CM (Common): Connect to the common terminal.

Parameter Settings

1. Enter the parameter setting interface on the control panel.
2. Locate the F3 parameter group and set F3.00 (X1 Terminal Function Selection) to 5 (Three-Wire Running Control).
3. Set F3.06 (Terminal Command Mode) to 2 (Three-Wire Mode 1) or 3 (Three-Wire Mode 2), depending on the control logic.
4. Save the parameters to enable external terminal forward/reverse control.

2. External Potentiometer Speed Control

The EH600A series supports speed control via an external potentiometer. The following steps outline the wiring and parameter settings:

Wiring

• AI1 (Analog Input 1): Connect to the signal terminal of the external potentiometer.
• GND (Ground): Connect to the ground terminal of the external potentiometer.

Parameter Settings

1. Enter the parameter setting interface on the control panel.
2. Locate the F0 parameter group and set F0.03 (Main Frequency Source X Selection) to 2 (AI1).
3. Set F3.08 (AI1 Minimum Input) and F3.10 (AI1 Maximum Input) according to the potentiometer’s output range.
4. Save the parameters to enable external potentiometer speed control.
