n8-04: Pole Attraction Time
There is normally no need to change this parameter from the default value. Sets the pole attraction time to detect the rotor
pole during the phase-Z pulse position tuning. Set this parameter to a large value if the motor vibrates during the phase-Z
pulse position tuning.
Note: This parameter is not available in models CIMR-A4A0930 and 4A1200.
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.
Note: This parameter is not available in models CIMR-A4A0930 and 4A1200.
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.
Note: This parameter is not available in models CIMR-A4A0930 and 4A1200.
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.
Note: This parameter is not available in models CIMR-A4A0930 and 4A1200.
n8-21: Motor Ke Gain
There is normally no need to change this parameter from the default value.
Sets the gain for speed estimation.
Note: This parameter is not available in models CIMR-A4A0930 and 4A1200.
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 CL
V/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 a 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.
