DC High Rush

What does FF80 mean?

The drive's supply voltage is excessive, exceeding 124% of the unit's voltage rating. When this occurs, the motor speed can rapidly accelerate (rush) to a trip level (40% of nominal speed), indicating a potentially damaging overvoltage condition for the drive and potentially the motor.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Investigate the power supply system for transient overvoltage conditions, grid fluctuations, or misconfigurations that could cause excessive voltage.
