No bus access to the parameter (Register 0007)

¿Qué significa 130 ?

The parameter attempted to be accessed through the communication bus (e.g., Modbus) via Holding Register 0007 is either not configured for bus access or is specifically restricted from external modification or readout. This ensures certain parameters can only be adjusted locally.

• Parameter P3-01 (Communication Protocol) set incorrectly or does not match the bus master.
• Parameter P7-02 (Register Access Permissions) configured as read-only or restricted for Register 0007.
• Drive operating in Local/Keypad control mode (Parameter P1-01), preventing remote bus writes.
• Incorrect Modbus register address mapping in the PLC/HMI, attempting to write to an invalid register.
• Communication timeout (Parameter P3-05) set too short for the bus master to establish a connection.

1. 1

   Verify Parameter P3-01 (Communication Protocol) matches the connected bus master's protocol (e.g., Modbus RTU).

2. 2

   Check Parameter P7-02 (Register Access Permissions) for Register 0007 to ensure write access is enabled.

3. 3

   Confirm the PLC/HMI is using the correct Modbus register address for the intended parameter (e.g., 0x0007).

4. 4

   Switch the drive control mode to Remote/Bus control using Parameter P1-01 if bus write access is required.

5. 5

   Monitor the communication bus status indicator on the drive keypad (e.g., 'COMM' LED) for activity.
