• If hunting, oscillation
C5-04 [ASR Integral occurs, increase the
Time 2 (I)] setting value.
Change the ASR
proportional gain and
ASR integral time in
accordance with the
output frequency.
Raise setting value in
increments of 0.010 when
vibration is likely to occur
due to poor machine
rigidity.
Refer to the motor's test
report or nameplate and
set E1-xx or E5-xx
correctly.
