13.12.7 Test operation mode
(1) Instructions for test operation mode
The test operation mode must be executed in the following procedure. If communication is interrupted
for longer than 0.5s during test operation, the servo amplifier causes the motor to be decelerated to a
stop and servo-locked. To prevent this, continue communication without a break, e.g. monitor the
status display.
