In wiring to power supply (outside of equipment) from MCCB, use an electric wire of 1.6 mm
diameter (2.0 mm

) or more both for main circuit and grounding.
Apply grounding class D (100 Ω or below) for grounding.
Do not tighten the ground wires together, but connect them individually.
Fastening torque of earth screws to be 0.49 to 0.98 N·m.
Routine maintenance and inspection are essential for proper and satisfactory
operation of the motor.
Notes to maintenance/inspection personnel
• Power-on/off operations should be done by the operators themselves for ensuring safety
in checking.
• Do not touch the motor while it is running or immediately after it stops because it gets hot
and stays hot for a while after power has been turned off.
• When testing the insulation resistance of the brushless amplifier with the megger,
disconnect the amplier from all associated devices. Performing megger testing without
rst disconnecting these devices will cause failure.

Insulation
resistance
tester
The resistance of motor should be 1 MΩ or higher when tested
with a 500 V megger.
Brushless motor: Across phase (U, V, W) and ground terminals
Noise Hearing
Noise level must not be different from the usual level. In
addition, abnormal noise such as rumbling noise must not be
heard.
Vibration By hand Free from abnormal vibration.
Grease
leakage
Visual check
Check that circumference of the motor and gear head are free
from oil and grease.
If grease leakage will cause problem, use grease sealing cover.
Installation

wrench
Check for loosening of bolt, and tighten additionally as
necessary.

environment
By sight
Check the ambient temperature and humidity, and make sure
that dirt, dust, or foreign substance is not found.
When disassembly, troubleshooting, etc., is needed,
be sure to contact our service department or the sales agent of purchase.
