14. COMMUNICATION FUNCTION
14 - 33
14.5.8 Test operation mode
POINT
The test operation mode is used to check operation. Do not use it for actual
operation.
If communication stops for longer than 0.5 s during test operation, the driver
decelerates to a stop, resulting in servo-lock. To prevent this, continue
communication all the time by monitoring the status display, etc.
Even during operation, you can switch the driver to the test operation mode. In
this case, switching to the test operation mode will shut off the base circuit to
coast the motor.
