Brake resistor

What does 7181 mean?

The drive detects an issue with the brake resistor, indicating it might be disconnected, physically damaged, or improperly sized. This prevents proper dissipation of regenerative energy, potentially leading to DC bus overvoltage and drive trips during deceleration.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Confirm that the brake resistor is appropriately dimensioned for the application's braking energy requirements and duty cycle.
