Test operation with servo motor
and machine connected
In this step, confirm that the servo amplifier and servo motor operate normally.
With the servo motor disconnected from the machine, use the test operation
mode and check whether the servo motor rotates correctly. Refer to section
4.5 for the test operation mode.
In this step, confirm that the servo motor rotates correctly under the
commands from the controller.
Make sure that the servo motor rotates in the following procedure.
