Hysteresis
The hysteresis value may be determined so as to allow a margin for timing the turning off of the HI/
LO limit comparison. Normally, it is turned on when the indicated value exceeds the HI limit and is
turned off when the indicated value falls below it. However, by setting the hysteresis, it is turned off
when the indicated value falls below the HI limit further lowered by the hysteresis value.
This function is effective to prevent chattering in such a case where signals fluctuate (vibrate)
subtly.

Torque and rotation speed can be set to HI/LO limit comparison, respectively.
However, this does not apply to alarm HI and LO limits.
