■ n8-02: Pole Alignment Current Level
No.
(Hex.)
Name Description
Default
(Range)
n8-02
(0541)
Pole Alignment Current
Level
Sets the current at the time of polar attraction as a percentage where E5-03 [motor rated current] is
100%. Usually it is not necessary to change this setting.
80%
(0 - 150%)
The drive uses the polar pull-in current to attract the rotor after it detects the initial rotor position. When you increase
the value of n8-02, the starting torque also increases.
• If the motor does not track correctly at the time of the polar attraction, increase the value in 10% increments.
• If the motor oscillates at the time of the polar attraction, decrease the value in 10% increments.

Observer Calculation Gain 2
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
Determined by n8-72
(0.0 - 1000.0)
Note:
When n8-72 = 0 [Speed Estimation Method Select = Method 1], the default value is 50.0. When n8-72 = 1 [Method 2], the default value is
150.0.
