NOTE 4: It will display “Auto Tuning Err” on the keypad when stopping by the fault of the

AC motor drive or human factor to show the failed detection. At this moment, please check
the connections of the wirings of the AC motor drives. If it displays “PG Fbk Error” on the
digital keypad, please change the setting of Pr.10-02 (if it is set to 1, please change it to 2).
If it displays “PG Fbk Loss” on the digital keypad, please check the feedback of Z-phase
pulse.

Pr.10-00
PG signal type

0: No function
1: ABZ
2: ABZ+Hall
3: SIN/COS+Sinusoidal
4: SIN/COS+Endat
5: SIN/COS
6: SIN/COS + Hiperface

Encoder settings: Pr.10-01~Pr.10-02

Detection for the magnetic pole position of motor
The detection method will be different by the setting of Pr.10-00 PG Signal Type.
The detection methods: (refer to Pr.10-00)

Setting 1 or 5: The AC motor drive will output short circuit to detect the position of the

electromagnetic pole. At this moment, the motor will generate a little noise.

Setting 2: The AC motor drive will detect the position of the electromagnetic pole by the

UVW signal of PG.

Setting 3: The AC motor drive will detect the position of the electromagnetic pole by the

sine signal of PG.

Setting 4: The AC motor drive will detect the position of the electromagnetic pole by the

communication signal of PG.
