■
C5-26: Motor 2 ASR Delay Time
No.
Name
(Hex.)
C5-26 Motor 2 ASR Delay
Time
(035B)
Increase this setting gradually in increments of 0.01 for loads with low rigidity or when oscillation is a problem.
■
C5-27: Motor 2 ASR Gain Switchover Freq
No.
Name
(Hex.)
C5-27 Motor 2 ASR Gain
Switchover Freq
(035C)
Switching the proportional gain and integral time in the low or high speed range can help stabilize operation . A
good switching point is 80% of the frequency where oscillation occurs or at 80% of the maximum output
frequency.
Note:
A multi-function input set for H1-xx = 77 [MFDI Function Select = ASR Gain Switch] takes priority over the ASR gain switching
frequency.
■
C5-28: Motor 2 ASR Integral Limit
No.
Name
(Hex.)
C5-28 Motor 2 ASR Integral
Limit
(035D)
■
C5-29: Speed Control Response
No.
Name
(Hex.)
C5-29 Speed Control
Response
(0B18)
If a high level of speed control responsiveness is necessary, set C5-29 = 1 and then adjust the speed control (ASR)
parameter.
0 : Standard
1 : High speed
■
C5-32: Motor 2 Integral Oper @ Acc/Dec
No.
Name
(Hex.)
C5-32 Motor 2 Integral
Oper @ Acc/Dec
(0361)
Enabling integral operation when driving a heavy load or a high inertia load may cause problems with overshoot
or undershoot at the end of acceleration and deceleration. Set C5-32 = 0 [Disabled] if there are problems of
overshooting or undershooting.
0 : Disabled
Integral operation is enabled during constant speed. Integral operation is not enabled during acceleration or
deceleration.

V/f CL-V/f OLV CLV AOLV
Sets the filter time constant for the time from the speed loop to the torque
command output. There is normally no need to change this parameter from
the default value.
V/f CL-V/f OLV CLV AOLV
Sets the frequency where the drive should switch between C5-21 [Motor 2
ASR Proportional Gain 1] and C5-23 [Motor 2 ASR Proportional Gain 2].
Sets the frequency where the drive should switch between C5-22 [Motor 2
ASR Integral Time 1] and C5-24 [Motor 2 ASR Integral Time 2] as well as
between C5-21 and C5-23.
V/f CL-V/f OLV CLV AOLV
Sets the upper limit for ASR in units of %. Sets the percentage of the rated
load.
V/f CL-V/f OLV CLV AOLV
Selects the responsiveness of speed control. Normally there is no need to
change this setting.
V/f CL-V/f OLV CLV AOLV
Enables or disables integral operation during acceleration and deceleration.
