6. Maintenance
Check the following items.
Turn off the power, and make sure rotating elements are
ZA-10A
1
stopped.
ZA-5A
1
Never work while rotating, or it may cause injury. When
ZA-2.5A
1
checking, turn off the power source, and make sure the
ZA-1.2A
1
rotating elements are stopped still. At this time, be careful
ZA-0.6A
not to have fingers or hand pinched.

1) When the powder is moist, the expected performance may not be exhibited.
Be careful not to admit water or oily material inside the clutch.
In particular, if used near the gear box, the oil may invade through the shaft,
and therefore perfect oil sealing is advised.
2) Deterioration of torque (aged deterioration) depends on the conditions of
use (slip rotational speed, heat dissipation). However, if the exciting current
is increased, deterioration can be prevented to some extent.
1500 1800
If the specified torque cannot be obtained at the rated current, replace the
powder.
To replace the powder, please contact our service network.
3) Check the coupling mounting bolts and others for looseness.

7. Troubleshooting
 Torque output is low.
 Torque is not
generated by passing
exciting current.
 Torque is generated
without passing
current.
 Torque fluctuates on
every rotation.
 Surface temperature
exceeds 100°C
In the event of a serious trouble or when replacing parts, call our agent,
service center, or sales office, by specifying the manufacturing serial number
together with the type name of the clutch.
For repair or disassembly services, please call our designated service
network.
Mitsubishi Electric is not responsible for any damage or trouble caused by
repair, disassembly or modification of the product by any third party other
than Mitsubishi or specified agent.
