■
C5-02: ASR Integral Time 1
No.
Name
(Hex.)
C5-02 ASR Integral Time 1
(021C)
RUN
An integral time that is too long will decrease the responsiveness of the speed control and decrease drive response
to dynamic changes in motor load. An integral time that is too short can cause oscillation.
■
C5-03: ASR Proportional Gain 2
No.
Name
(Hex.)
C5-03 ASR Proportional
Gain 2
(021D)
RUN
The speed response increases as the weight of the load increases. Usually, the gain increases with larger loads.
Too much gain will cause 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 will decrease the responsiveness of the speed control and decrease drive response
to dynamic changes in motor load. An integral time that is too short can cause oscillation.
■
C5-05: ASR Limit
No.
Name
(Hex.)
C5-05 ASR Limit
(021F)
If the motor rated slip is high, it could be necessary to increase the setting to provide correct motor speed control.
Use U6-04 [ASR Output] to make sure that ASR is operating at the limit set in this parameter. When ASR is
operating at the limit, correctly set the PG signal and these parameters before you make changes to C5-05:
• F1-01 [Encoder 1 Pulse Count (PPR)]
• F1-12 [Encoder 1 Gear Teeth 1]
• F1-13 [Encoder 1 Gear Teeth 2]
■
C5-06: ASR Delay Time
No.
Name
(Hex.)
C5-06 ASR Delay Time
(0220)
If you have a load with low rigidity or if oscillation is a problem, increase this setting in 0.01 unit increments.

V/f CL-V/f OLV CLV AOLV
Sets the ASR integral time.
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. Usually it is not necessary to change this setting.
