Motor Inertia
Acceleration Time
Sets the length of time for the motor to accelerate from the stopped to the maximum
frequency with a single motor at the rated torque. Inertia Tuning automatically sets the
motor acceleration time.

Pull-in Current Switching
Speed
Parameter n8-51 [Pull-in Current @ Acceleration] , is in effect when the output frequency
is ≤ n7-10 , where the speed is set as a percentage of rated speed.
Note:
•
The value set in n8-51 [Pull-in Current @ Acceleration] is enabled for speeds that
are not higher than n7-10 during deceleration. The value set in b8-01 [Energy Saving
Control Selection] is enabled for speeds higher than n7-10 .
•
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.
