Routine maintenance and inspection of the driver and motor are essential for the
proper and safe operation.
Notes on Maintenance and Inspection
1) Turn on and turn off should be done by operators or inspectors themselves. When es-
tablishing a system using safety functions, completely understand the applicable safety
standards and the operating instruction manual or technical documents for the product.
2) Internal circuit of the driver is kept charged with high voltage for a while even after
power-off. Turn off the power and allow 15 minutes or longer after LED display of the
front panel has gone off, before performing maintenance and inspection.
3) Disconnect all of the connection to the driver when performing megger test (Insulation
resistance measurement) to the driver, otherwise it could result in breakdown of the
driver.
4) Do not use benzine, thinner, alcohol, acidic cleaner and alkaline cleaner because they
can discolor or damage the exterior case.
