Brake resistor short-circuited

What does 25 mean?

The external brake resistor connected to the drive has developed a short circuit, disabling the brake function. This prevents the drive from dissipating regenerative energy, potentially leading to a DC overvoltage trip during deceleration.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Check the wiring connecting the brake resistor to the drive for any signs of short circuits or damage.

2. 4

   Replace the brake resistor if it is confirmed to be short-circuited, ensuring the replacement is of the correct ohmic value and power rating.
