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.
