Pull-in Current
Switching Speed
Sets the speed range to operate with the pull-in current command. Drive rated frequency
= 100% value. If there is a large quantity of oscillation when you operate in the low
speed range, increase the setting value.

Drv Mode Switch
Hysteresis Band
Usually it is not necessary to change this setting. Sets the hysteresis level for Switching
Speed set in n7-10 [Pull-in Current Switching Speed].
When the speed is lower than n7-10 + n7-11 during acceleration, the drive enables pull-
in current.
Note:
• When the drive accelerates, it enables these settings:
–Motor speed ≤ n7-10 + n7-11: n8-51 [Pull-in Current @ Acceleration]
–Motor speed > n7-10 + n7-11: b8-01 [Energy Saving Control Selection]
• If there is a large quantity of oscillation when you operate in the low speed range,
increase the setting value.
• When it is most important to save energy in the low speed range, decrease the
setting value.
