| P17.03 | Low speed zone definition | 0.1% ~ 60.0% | 10.0% | ★ |
| P17.07 | High frequency injection amplitude | 5% ~ 50.0% For the amplitude of high-frequency signal injection, the larger the set value, the higher the accuracy of position identification, but the greater the noise of the motor. The set value should be as small as possible when the accuracy meets the requirements. | 20.0% | ☆ |
| P17.11 | Operation mode in low speed in SVC | 0: normal way 1: High frequency injection operation | 0 | ★ |
| P17.12 | No load current in low speed in SVC | 0.0% ～ 100.0% | 20% | ☆ |
| P17.13 | No load current in high speed in SVC | 0.0% ～ 50.0% | 2.0% | ☆ |
| P17.18 | MTPA control | 0:disable 1:enable MTPA is the maximum torque current ratio control. Enabling MTPA can reduce the motor current when SVC and VC are running under load. | 0 | ☆ |
| P17.19 | MTPA control adjust time | The smaller the set value, the faster the MTPA will act, it will cause current oscillation if set value too small | 0.500 | ☆ |
