■ C5-12: Integral Operation @ Accel/Decel
No.
(Hex.)
Name Description
Default
(Range)
C5-12
(0386)
Integral Operation @ Accel/
Decel
Sets ASR integral operation during acceleration and deceleration.
0
(0, 1)
Set this parameter to 1 to keep the motor speed near the frequency reference during operation and acceleration/
deceleration.
Note:
• When A1-02 = 0 [Control Method Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train Function = Speed Feedback (V/F Control)] to
enable this parameter.
• If you enable integral control, overshoot or undershoot can occur when acceleration or deceleration complete. If there are problems with
overshooting and undershooting, set this parameter to 0.
0 : Disabled
The drive will not enable integral operation during acceleration or deceleration. The drive always enables integral
operation during constant speed.
1 : Enabled
Integral operation is always enabled.
■ C5-29: Speed Control Response
No.
(Hex.)
Name Description
Default
(Range)
C5-29
(0B18)
Expert
Speed Control Response
Sets the level of speed control responsiveness. Usually it is not necessary to change this setting.
1
(0, 1)
If a high level of speed control responsiveness is necessary, set C5-29 = 1, then adjust the speed control (ASR)
parameter.
0 : Standard
1 : High Performance 1
■ C5-39: ASR Primary Delay Time Const 2
No.
(Hex.)
Name Description
Default
(Range)
C5-39
(030D)
ASR Primary Delay Time
Const 2
Sets the filter time constant used when the torque reference is output from ASR. Usually it is not
necessary to change this parameter.
0.000 s
(0.000 - 0.500 s)
If you have a load with low rigidity or if oscillation is a problem, increase this setting in 0.01 unit increments.
◆ C6: Duty & Carrier Frequency
C6 parameters are used to set the selection of drive duty rating, selection of carrier frequency, and upper and lower
limits of carrier frequencies.
■ C6-01: Normal / Heavy Duty Selection
No.
(Hex.)
Name Description
Default
(Range)
C6-01
(0223)
Normal / Heavy Duty
Selection
Sets the drive duty rating.
1
(0, 1)
0 : Heavy Duty Rating
The overload tolerance is 150% of the rated output current for 60 seconds.
1 : Normal Duty Rating
The overload tolerance is 110% of the rated output current for 60 seconds.
