Is a large amount of dust or abrasion powder accumulated?
If a large amount of dust or abrasion powder collects in the gaps or sliding parts of the
clutch / brake, it may cause malfunction.
Is there rust?
Make sure that the clutch and brake are free of rust. Especially when used in areas with
high salt content such as beach areas, rusting may be promoted depending on the
installation environment. In this case, please consider implementing rust prevention
measures.
Is there any abnormality in the operation?
When the clutch is ON, check that the input shaft and output shaft rotate smoothly in
the connected state, and when the brake is ON, check that the output shaft is in the
stopped state and the input shaft rotates smoothly.
Is the exciting voltage normal?
For clutches and brakes, the engagement time and torque change when the exciting
voltage fluctuates. Also, if the exciting voltage falls below the specified value, the clutch
and brake will not be able to attract, so be sure to supply the specified voltage. Even if
the power supply voltage is as specified, if the circuit is long, the voltage will drop due to
line resistance, so check the voltage at the clutch / brake terminal when the power is on.
