Brake Resistor Wiring Fault

What does 7111 mean?

The brake resistor is incorrectly wired. This can lead to improper braking operation, potential damage to the resistor or drive, and ineffective energy dissipation during deceleration, creating unsafe operating conditions and poor speed control.

Complete Troubleshooting Guide

1. 1

   Check the brake resistor connection against the drive's wiring diagram for correct polarity and terminal assignments.

2. 2

   Ensure the brake resistor itself is not physically damaged or has internal open circuits.

3. 3

   Verify the continuity of the wiring from the drive to the brake resistor.
