I. Introduction to the Operation Panel Functions and Parameter Settings

Operation Panel Functions

The LS Inverter SV-iGxA series features an intuitive operation panel that includes RUN, STOP/RESET, up and down arrow keys, as well as a confirmation key. The panel’s 7-segment LED display provides clear visual feedback on operational data and parameter settings. Here’s a detailed look at the functions of the operation panel:

• RUN Key: Starts the motor when pressed.
• STOP/RESET Key: Stops the motor during operation and resets fault conditions when pressed after a fault occurs.
• Arrow Keys: The up and down arrow keys are used to navigate through parameters and adjust their values.
• Confirmation Key: Confirms parameter settings and saves changes.
• 7-Segment LED Display: Shows operational data such as output frequency, output current, and fault codes.

Parameter Initialization

To initialize the parameters to their factory default settings, follow these steps:

1. Navigate to Parameter H93: Use the arrow keys to select parameter H93 (Parameter Initialization) in the function group 2.
2. Set Initialization Value: Press the confirmation key to enter the setting, then use the arrow keys to select the desired initialization level (e.g., 1 for initializing all parameter groups).
3. Confirm Initialization: Press the confirmation key again to save the setting and initialize the parameters.

Reading, Writing, and Copying Parameters

The SV-iGxA series supports reading and writing parameters using a remote panel or communication interface.

• Reading Parameters:
  1. Navigate to parameter H91 (Parameter Read) in the function group 2.
  2. Press the confirmation key to initiate the parameter read process.
  3. Follow the prompts on the remote panel or software interface to complete the read operation.
• Writing Parameters:
  1. Navigate to parameter H92 (Parameter Write) in the function group 2.
  2. Press the confirmation key to initiate the parameter write process.
  3. Follow the prompts on the remote panel or software interface to upload the new parameter settings to the inverter.

Setting a Password and Locking Parameters

To enhance security, the SV-iGxA series allows users to set a password and lock specific parameters.

• Registering a Password:
  1. Navigate to parameter H94 (Password Registration) in the function group 2.
  2. Press the confirmation key to enter the setting.
  3. Use the arrow keys to input the desired password (in hexadecimal format).
  4. Press the confirmation key to save the password.
• Locking Parameters:
  1. Navigate to parameter H95 (Parameter Lock) in the function group 2.
  2. Press the confirmation key to enter the setting.
  3. Use the arrow keys to select the desired lock level (e.g., locking all parameters by setting H95 to 0xFFFF).
  4. Press the confirmation key to save the setting and lock the parameters.

II. Terminal Control and Potentiometer Speed Regulation

Terminal Forward/Reverse Control

To achieve forward/reverse control via terminal inputs, the following parameters need to be configured:

• drv (Drive Mode): Set to 1 to enable terminal control.
• drC (Motor Rotation Direction Selection): Select the desired rotation direction (F for forward, r for reverse).
• I17-I18 (Multi-Function Input Terminal Definitions): Assign the FX (forward) and RX (reverse) commands to specific terminals (e.g., P1 for FX and P2 for RX).

Required Wiring:

• FX Terminal: Connect to a normally open (NO) contact to start the motor in the forward direction.
• RX Terminal: Connect to a normally open (NO) contact to start the motor in the reverse direction.
• CM (Common) Terminal: Provide a common ground connection for all input terminals.

Potentiometer Speed Regulation

For speed regulation using a potentiometer, the following parameters need to be configured:

• Frq (Frequency Mode): Set to 3 to enable potentiometer input for frequency control.
• I6-I10 (V1 Input Parameters): Configure the voltage range and corresponding frequency for the potentiometer input.
  • I7 (V1 Input Minimum Voltage): Set to the minimum voltage output by the potentiometer.
  • I8 (V1 Input Minimum Frequency): Set the frequency corresponding to the minimum voltage.
  • I9 (V1 Input Maximum Voltage): Set to the maximum voltage output by the potentiometer.
  • I10 (V1 Input Maximum Frequency): Set the frequency corresponding to the maximum voltage.

Required Wiring:

• V1 Terminal: Connect to the output of the potentiometer.
• CM Terminal: Provide a common ground connection for the V1 terminal.
• 10V Terminal (if applicable): Provide a 10V reference voltage for the potentiometer (not required for potentiometers with built-in reference voltage).

By configuring the above parameters and wiring the terminals correctly, the SV-iGxA series inverter can be easily controlled via external inputs for forward/reverse operation and speed regulation using a potentiometer.
