N8: Pm Motor Control Tuning - YASKAWA AC Drive-A1000 Technical Manual

n n6-05: Online Tuning Gain
Sets the compensation gain for the voltage correction in the Online Tuning function (n6-01 = 2).
Although this parameter rarely needs to be changed, increase the set value in steps of 0.1 if an overload fault occurs during
voltage correction
No.

n8: PM Motor Control Tuning

Note: PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
These parameters adjust the control performance in the vector control modes for permanent magnet motors.
n n8-01: Initial Rotor Position Estimation Current (AOLV/PM)
Note: PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
Sets the current used for the initial rotor position estimation as a percentage of the motor rated current.
No.
n8-01
n n8-02: Pole Attraction Current (AOLV/PM)
Note: PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
Sets the current that is 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 setfting to increase the starting torque.
No.
n8-02
n n8-35: Initial Rotor Position Detection Selection (AOLV/PM, CLV/PM)
Note: PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
Selects how the rotor position is detected at start.
Note: 1. 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.
2. 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).
No.
n8-35
Setting 0: Pull in
Starts the rotor using pull-in current.
Setting 1: High Frequency Injection
High frequency is injected to detect the rotor position. Some noise may be generated from the motor at start.
Setting 2: Pulse injection
A pulse signal is injected into the motor to detect the rotor position.
n n8-45: Speed Feedback Detection Control Gain (OLV/PM)
Note: PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
Sets the gain for internal speed feedback detection control. Although this parameter rarely needs to be changed, adjustment
may be necessary under the following conditions:
• Increase this setting if motor oscillation or hunting occurs.
• Decrease this setting in increments of 0.05 to decrease drive responsiveness.
No.
