POINTS
(1) Make note of servo motor module names before the servo motor is mounted
on a machine. The servo motor rating plate may not be visible after the servo
motor is mounted.
(2) When the servo amplifier, servo motor is first turned on, check the operation
before the servo motor is mounted on a machine to avoid an unexpected
accidents such as machine breakage.
Axis No. and error description of servo amplifier which
detected errors are displayed on initial check screen.
The system must have a mechanical allowance so
that the machine itself can stop even if the stroke
limits switch is passed through at the max. speed.
Execute the test operation in the system that it is
low-speed as much as possible and put forced
stop, and confirm the operation and safety.
