Heavy Load Operation Adjustment
9. Load operating test
B1. Low-frequency loading performance is below 1/10 of rated frequency:
a. If the low-frequency loading performance is insufficient, or the rotor speed is not smooth,
increase Pr.10-31 (Current command of I/F mode).
b. If the low-frequency current is large, decrease Pr.10-31 (Current command of I/F mode).
B2. Test the with-load accelerating performance:
When the motor operates in 1/10 of rotor speed and above, if the speed cannot follow the
acceleration time during accelerating, or the current stalls, increase Pr.07-38 (PMSVC
voltage feedback forward gain).
10. Stability test at constant speed operation: if the motor operates stably at constant speed
a. If the motor output rotor speed presents periodic low-frequency wave, increase Pr.10-34
(PM sensorless speed estimator low-pass filter gain), or increase Pr.10-32 (PM FOC
sensorless speed estimator bandwidth).
b. If the output frequency reflects high-frequency vibration, decrease Pr.10-34 or decrease
Pr.10-32.
