The motor for the displayed axis is not turning when commanded. This indicates a failure in motor activation, power delivery, or mechanical blockage.
Click steps to track your progress.
Verify that a valid run command, target position, or speed is being sent to the affected axis by the NC program or manual controls.
Check the motor power cables for continuity, correct connection to the drive and motor terminals, and absence of damage.
Inspect the drive for the specified axis for any fault indicators, error messages, or signs of power loss.
Measure the supply voltage at the drive input and the output voltage/current to the motor when a run command is active to confirm power delivery.
Check for any mechanical binding or blockage in the axis mechanics that physically prevents the motor from rotating.
