POINT
The test operation mode is used to confirm operation. Do not use it for actual
operation.
If communication stops for longer than 0.5s during test operation, the servo
amplifier decelerates to a stop, resulting in servo lock. To prevent this, continue
communication all the time, e.g. monitor the status display.
Even during operation, the servo amplifier can be put in the test operation mode.
In this case, as soon as the test operation mode is selected, the base circuit is
shut off, coasting the servo amplifier.
