Maintenance
■
Servo motor operation is unstable or lower speed than the specified velocity command.
■
Servo motor rotates only moment, and stops.
* When performing the work for correction and investigation processing about wiring, be sure to
intercept power supply.
■
Servo motor runs away.
* When performing the work for correction and investigation processing about wiring, be sure to
intercept power supply.
■
Servo motor is vibrating.
■
Occurs over shoot/ under shoot when starting / stopping.
Investigation Assumed causes and corrective actions
