(0562)
When A1-02 = 7 [Control Method Selection = PM Closed Loop Vector Control] is set, the initial motor magnetic
pole detection operates for the first instance after the power supply is turned on. After that, rotor position is
calculated from the encoder signal and saved until the drive is switched off.
0 : Pull-In
Starts the rotor with pull-in current.
1 : High frequency injection
High frequency is injected to detect the rotor position. Using this setting may cause significant excitation sound
when motors start.
2 : Pulse injection
Inputs the pulse signal to the motor to detect the position of the rotor.
Note:
• Select a value of 0 if using SPM motors. Values between 0 to 2 can be selected if using IPM motors.
• Always carry out a prior evaluation of the drive and machinery combination being used for the application when setting n8-35 = 1 or 2.
The motor may rotate in the direction that is opposite that of the direction of the Run command if the polarity direction is detected
mistakenly.
