How do I fix an F12 Brake Chopper Fault code for a DG1 drive?

The purpose of the brake chopper fault is to indicate when the brake chopper is enabled and there is a resistor connected to see if it is functioning properly. The drive sends 50% of its duty cycle output wave to the brake chopper, in addition the drive captures the feedback signal which will indicate if the brake chopper is working properly. If the feedback is different than the signal sent out the drive will indicate a brake chopper fault. From here it is suggested to check the brake resistor to be sure it ohms out correctly. If things there check okay, perform static checks on the Brake as listed below.
