 PM FOC+PG With-load starting adjustment procedure
 With-load Operation Adjustment:
C1. Low-frequency load performance, when the drive operates under ASR1/ASR2 switch
frequency (Pr.11-02):
a. If the low-speed frequency cannot start-up with load or the rotor speed is not smooth,
increase Pr.11-03 (ASR1 low-speed bandwidth), or increase Pr.11-01 (Per-unit system
inertia).
b. If an oscillation or over current (oc) error occurs at low-speed frequency, decrease
Pr.11-03 (ASR1 low-speed bandwidth) or decrease Pr.11-01 (Per-unit system inertia).
