5. Torque adjustment
Use within rated torque.
If used over the rated torque, not only the
performance deteriorates, but also mechanical
breakage or injury may be caused. Hence, use with
rated torque. In particular, it must be noted that a
torque over the rating may be cause even if used at
the rated current, and therefore check the current-
torque characteristic, and adjust the exciting current.
(In the course of use, the torque gradually declines,
and therefore in manufacturing, a proper allowance
is considered initially.)
The relation of torque and exciting current is almost proportional as shown
in Fig. 3, and therefore by adjusting the current, the torque can be easily
adjusted.
Set to a proper value in consideration of the finish of the product or
working condition.
Use within the allowable heat dissipation.
If used over allowable heat dissipation, the clutch
may be extremely heated, and the working surface
may be extremely hot and red. As a result, a fire may
be caused. In addition, the performance may be
deteriorated. Be sure to use within the allowable heat
dissipation (refer to Fig. 4).

Check the following items.
Turn off the power, and make sure rotating elements are
stopped.
Never work while rotating, or it may cause injury. When
checking, turn off the power source, and make sure the
rotating elements are stopped still. At this time, be careful
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) The powder replacement timing cannot be indicated clearly because
the powder life varies depending on the conditions of use (slip rotation
speed, heat dissipation). Judge the replacement timing when the torque
decreases to 70% or less of the initial value. However, it is actually
difficult to check the torque.
Even if the torque has decreased, it increases when the exciting current
increases. Therefore, 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.
