Warning /Alarm in 27 VLT FC301/ FC302 : Brake chopper short-circuited - The brake transistor is monitored during operation, and if a short circuit occurs, the brake function is disabled, and a warning is issued.
1. The drive is still operational, but since the brake transistor has short-circuited, substantial power is transmitted to the brake resistor, even if it is inactive.
2. Remove the power to the drive and remove the brake resistor.
