C5-03: ASR Proportional Gain 2
No.
Name
(Hex.)
C5-03 ASR Proportional
Gain 2
(021D)
RUN
The speed response increases with the weight of the load. Normally, the gain increases with larger loads.
Excessive gain causes vibration.
■
C5-04: ASR Integral Time 2
No.
Name
(Hex.)
C5-04 ASR Integral Time 2
(021E)
RUN
An integral time that is too long reduces the responsiveness of the speed control and weakens repulsion against
external force. An integral time that is too short can cause oscillation.
■
C5-05: ASR Limit
No.
Name
(Hex.)
C5-05 ASR Limit
(021F)
RUN
If the motor rated slip is high, the setting might need to be increased to provide proper motor speed control. Use
U6-04 [ASR Output] to determine if ASR is working at the limit set to C5-05. If ASR is working at the limit,
make sure F1-01 [PG 1 Pulses Per Revolution], F1-12 [PG 1 Gear Teeth 1], and F1-13 [PG 1 Gear Teeth 2], and
the PG signal are set correctly before making further changes to C5-05.
■
C5-06: ASR Delay Time
No.
Name
(Hex.)
C5-06 ASR Delay Time
(0220)
RUN
Increase this setting gradually in increments of 0.01 for loads with low rigidity or when oscillation is a problem.
■
C5-07: ASR Gain Switchover Frequency
No.
Name
(Hex.)
C5-07 ASR Gain
Switchover
(0221)
Frequency
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.

V/f CL-V/f OLV CLV AOLV
Sets the gain to adjust ASR response.
V/f CL-V/f OLV CLV AOLV
Sets the ASR integral time.
V/f CL-V/f OLV CLV AOLV
Sets the ASR output limit as a percentage of E1-04 [Maximum Output
Frequency].
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 C5-01 [ASR
Proportional Gain 1] and C5-03 [ASR Proportional Gain 2] as well as
between integral time 1 and 2 (C5-02, C5-04). Sets the frequency where the
drive should switch between C5-02 [ASR Integral Time 1] and C5-04 [ASR
Integral Time 2] as well as between C5-01 and C5-03.
