C2. With-load accelerating performance testing in heavy-load status, accelerate the motor to the
rated rotor speed according to the acceleration time.
- If the motor rotor speed 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); if the response speed is still not enough, increase 10% of the per-unit
system inertia for Pr.11-01 each time.
- If an excessive acceleration causes an oscillation or ocA error, decrease Pr.11-04
(ASR2 high-speed bandwidth) and Pr.11-03 (ASR1 low-speed bandwidth).
