 Load Operation Adjustment
10. Load operating test
B1. Low-frequency loading performance, when the switch frequency is below Pr.10-39:
a. When the low-frequency cannot start the motor with load, or the rotor speed is not smooth,
increase Pr.11-03 (ASR1 low-speed bandwidth) or Pr.11-01 (Per-unit of system inertia); if
the above adjustment cannot meet the requirement, then increase Pr.10-32 (PM FOC
sensorless speed estimator bandwidth).
b. When frequency outputs, low-frequency operating current is large or an oc error occurs,
decrease Pr.11-03 and Pr.11-01; or decrease Pr.10-32.
B2. Acceleration performance test under heavy-load status, accelerate the motor to rated
rotor speed according to the acceleration time:
a. If the motor cannot follow the acceleration time, and the response is too slow, increase
Pr.11-04 (ASR2 high-speed bandwidth) and Pr.11-03 (ASR1 low-speed bandwidth).
b. If an excessive acceleration causes vibration or ocA error, decrease Pr.11-04 and
Pr.11-03.
11. 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.
