You should check the driver every 3 months or 6 months according to the actual environment,
thus could lower fault risks and maintain a long-term stable operation.
General Inspection:
◇
whether screws of control terminals are loose. If so, tighten them with a screwdriver;
◇
whether the main circuit terminals are properly connected; whether the cable or copper bar
joints and screws are over heated;
◇
whether the power cables and control cables are damaged, check especially for any wear on
the cable insulation;
◇
whether the connecting of power cable and cold pressing joint is loose, whether the insulating
tapes around the joint are aged or stripped;
◇
clear the dust on PCBs and air ducts, and take anti-static measure;
◇
before performing insulation tests to the driver, dismantle the wiring between the driver and
the power supply, the driver and motor, and all main circuit input/output terminals should
be short-circuited with conductors. Then proceed insulation test to the ground. Please use
qualified 500V Mega-Ohm-Meter (or with corresponding voltage shift of insulation tester);
please do not use faulted meter. Insulation test of single main circuit terminal to ground is
prohibited, or the driver can be damaged. After testing, remember to dismantle all the wire
that short-circuit main circuit terminals.
◇
if performing insulation test to the motor, be sure to disconnect the cables between the driver
and it. Otherwise, the driver might be damaged.
