Motor Wiring Detection
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.
Motor Brake Enable Delay Time
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 CME2, but shows the timings in the same colors as the Brake setting
screen.
