ETECTION
When a brake is in use, the drive can check for a disconnected motor. Upon enable, the drive will apply current to the motor
output while keeping the brake engaged for the Brake Hold Time on Enable. If no current can be detected in the windings,
the brake will not be released and a Wiring Detection Fault will occur. If the motor is connected and current can be detected,
the brake will be released after the programmable time expires.

The programmable value in the Motor Wiring Detection also sets the time between the activation of the brake and PWM
outputs of the drive.
•
When the value is positive, the PWM outputs will turn on when the drive is enabled and the brake will
be released after the programmable delay expires.
•
When the value is negative, the brake is released immediately when the drive is enabled and the PWM
outputs are enabled after the programmable delay expires.
The graphic below is not part of CME, but shows the timings in the same colors as the Brake setting screen.
