Communication Interruption (Keypad)

What does COME mean?

The communication link between the remote keypad and the soft starter has been interrupted. This message flashes after 20 retries within a 50 ms timeout, indicating a loss of connection.

Complete Troubleshooting Guide

1. 1

   Check the physical RS485 communication wiring between the keypad and the soft starter for loose connections, damage, or improper shielding.

2. 2

   Verify the Modbus communication settings (address, baud rate, parity) on both the keypad and soft starter are correctly matched.

3. 3

   Inspect the Modbus network for excessive noise or other devices causing interference.
