Warning /Alarm 27 in danfoss VLT FC360 drive : Brake IGBT/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.
