II. PM FOC+PG adjustment flowchart for operation without load / with light load
B1.Accelerated
rated frequency
stable?
Increase ASR1 low-speed bandwidth
Pr.11-03
Increase ASR2 high-speed bandwidth
Pr.11-04
The rotor speed cannot
follow the accel. time
Decrease ASR1 low-speed bandwidth
Pr.11-03
Decrease ASR2 high-speed bandwidth
Pr.11-04
High-frequency oscillation
of output frequency
B2. Is the max.
output frequency
reachable?
Increase ASR2 high-speed
bandwidth Pr.11-04
Oscillation or motor stall at
max. rotor speed
NO
NO
11. Running Test
with Load
YES
YES
9.No-load
Trial Run
a. Set speed regulator ASR
Pr.11-00=1 ASR auto-tuning
b. No-load/ Light-load started,
auto accel./decel. testing
Set 10Hz frequency
command to proceed
encoder running test
A1. Start running in
the reverse direction?
Set Pr.10-02 input =2
(Phase B leads 90 degree
in a forward run
command the phase A)
RUN
A2. PGFx error or
abnormal speed?
Refer to Chapter 14
“Error Code” for
further treatment
PGF Error Type:
PGF1: PG feedback error
PGF2: PG feedback loss
PGF3: PG feedback stall
PGF4: PG slip error
PGF5: PG hardware error
YES
YES
NO
NO
