Maintenance/Inspection
• Routine maintenance and inspections are essential for proper and satisfactory operation of the driver
and motor.
Notes to Maintenance/Inspections Personnel
(1) Power-on/off operations should be done by the operators themselves.
(2) For a while after power off, the internal circuits is kept charged at higher voltage. Inspections should be done a
while (about 10 minutes), after the power is turned off and the LED lamp on the panel is extinguished.
(3) When conducting meager test (to measure insulation resistance) on the servo driver, disconnect all the connec-
tions from the driver. Conducting the test as connected would cause trouble of the driver.
