■
n8-02: Pole Attraction Current
Sets the current applied to pull the rotor into position after the initial rotor position estimations are complete. The value is
set as a percentage of the motor rated current. Increase this setting in order to increase the starting torque.
Note:
This parameter is available in AOLV/PM or CLV/PM.
■
n8-11: Induction Voltage Estimation Gain 2
There is normally no need to change this parameter from the default value.
Sets the gain for speed estimation.
■
n8-14: Polarity Compensation Gain 3
There is normally no need to change this parameter from the default value.
Sets the gain for speed estimation.
■
n8-15: Polarity Compensation Gain 4
There is normally no need to change this parameter from the default value.
Sets the gain for speed estimation.
■
n8-21: Motor Ke Gain
There is normally no need to change this parameter from the default value.
Sets the gain for speed estimation.
■
n8-35: Initial Rotor Position Detection Selection
Selects how the rotor position is detected at start.
Note: 1.
This parameter is available in AOLV/PM or CLV/PM.
2.
In CLV/PM, the drive performs a magnetic pole search the first time it starts the motor. After that, rotor position is calculated from the
PG encoder signal and saved until the drive is switched off. Parameter n8-35 determines how this initial pole search operates.
3.
High Frequency Injection and pulse injection for rotor position detection (n8-35 = 1 or 2) can be used with IPM motors only. When
using an SPM motor, select the pull in method to find the initial position of the rotor (n8-35 = 0).
Setting 0: Pull in
Starts the rotor using pull-in current.
Setting 1: High Frequency Injection
High frequency is injected in order to detect the rotor position. Some noise may be generated from the motor at start.
