A27 - Brake Chopper Short Circuit fault in danfoss drive

A27 - Brake Chopper Short Circuit fault in danfoss drive

Cause: The brake transistor (chopper) is short-circuited, disabling the braking function.
Solution:

• A shorted brake chopper often requires replacement of the power board or the entire drive.
• This fault can be caused by a shorted brake resistor, so inspect the resistor as well.
