Test Operation Mode - Mitsubishi Electric MELSERVO-J5 User Manual

Test operation mode

Even during operation, the servo amplifier can be switched to the test operation mode. In this case, switching to the test
operation mode will shut off the base circuit to coast the servo motor.
Precautions
• The test operation mode is designed for checking operation. Do not use it for an actual operation.
• If communication stops for 0.5 s or longer during test operation, the servo motor decelerates to a stop, resulting in servo-
lock. To prevent this, keep the communication all the time by monitoring the status display, etc.
