n8: PM MOTOR CONTROL TUNING

n8 parameters are used to make adjustments when controlling PM motors.

PolPos Detection Current
n8-01
(0540)
Expert
The drive uses the Initial Rotor Position Estimated Current to detect the initial position of rotors.
Use the "Si" value on the motor nameplate, if available.

n8-02: Pole Align Current Level
No.

(Hex.)
Pole Align Current Level
n8-02
(0541)
Expert
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.

Note:
When n8-72 = 1 [Spd Obs. Method Selection = Method 1], the default value is 50.0. When n8-72 = 2 [Method 2], the default value is
150.0.

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets, as a percentage, the Initial Rotor Position Estimated Current, taking the E5-03 [PM Mot
Rated Current (FLA)] as the 100% value. Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the current at the time of polar attraction as a percentage where E5-03 [PM Mot Rated
Current (FLA)] is 100%. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
