6. Troubleshooting and check
6-6
- When measuring electric power: Measure the electric current type by the three-wattmeter
method.
- Other instruments: When using an oscilloscope or digital bolt meta, please use it without
touching the ground. Use a meter input current of 1 mA or less.
6.3. Check
Caution
When checking the unit, always turn off the power and wait for more than 10 minutes to
pass before checking the unit because charged voltage can remain in DC Link capacitor to
cause an accident.
- Check any pieces of wire, dust, particles accumulated inside and clean appropriately.
- Check whether the screw of the terminal is loose and check whether they are tightened.
- Check if there are problems of parts (discoloration, damage, disconnection).
For the connection test of the control circuit, use the high resistance range on the tester, and
do not use a megger or buzzer.
- Check whether the cooling fan is operating normally.
- Check if there are any abnormal sounds (motor bearing, brake part).
- Check whether there are any damages or cracks to the cables (Especially detector cable).
Especially during operation, execute periodical checks according to the using condition during
operation.
- Check and correct any misalignment of center of load connecting axis.
