gral time when the same val-
ues cannot be used for both
high-speed and low-speed
operation.
ASR primary delay
time (C5-06)
• Controlling hunting
and vibration
0.010 s
0.04 to
0.020 s
Increase the setting if
machine rigidity is low and
the system vibrates easily.
(Enabled in the range 0 to
35 Hz. Refer to Procedure
for Increasing the Speed
Response below.)

0.010 s
0.010 to
0.035 s
Increase the setting if
machine rigidity is low and
the system vibrates easily.
(Enabled above 35 Hz. Refer
to Procedure for Increasing
the Speed Response below.)
Integral time of speed
estimator (N4-07)
• Speed response
• Controlling hunting
and vibration
0.030 ms
0.015 to
0.060 ms
(Enabled below the N4-11
setting.)
• Reduce the setting if speed
response is slow. (Typi-
cally, reduce in intervals of
0.05. Refer to Procedure
for Increasing the Speed
Response below.)
• Increase the setting if hunt-
ing or vibration occurs.
High-speed propor-
tional gain of speed
estimator (N4-10)
• Speed response
• Controlling hunting
and vibration
15 10 to 60
(Enabled below the N4-11
setting.)
• Increase the setting if
speed response is slow.
(Typically, increase in
intervals of 5. Refer to
Procedure for Increasing
the Speed Response
below.)
• Reduce the setting if hunt-
ing or vibration occurs.
Carrier frequency
selection (C6-11)
• Reducing motor
magnetic noise
• Controlling hunting
and vibration at low
speeds (3 Hz or less)
Depends
on the
capacity.
Default
value
• Increase the setting if
motor magnetic noise is
high.
• Reduce the setting if hunt-
ing or vibration occurs at
low to mi
ddle-range
speeds.
