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.
