C2. With-load accelerating performance testing in heavy-load status, accelerate the motor to the
rated rotor speed according to the acceleration time.
a. 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.
b. 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).
