■
C5-04: ASR Integral Time 2
No.
(Hex.)
Name Description
Default
(Range)
C5-04
(021E)
RUN
ASR Integral Time 2
Sets the ASR integral time.
Determined by A1-02
(0.000 - 60.000 s)
When you increase the integral time, the responsiveness will decrease. An integral time that is too short can cause
oscillation.
■
C5-06: ASR Delay Time
No.
(Hex.)
Name Description
Default
(Range)
C5-06
(0220)
ASR Delay Time
Sets the filter time constant of the torque reference output from the speed loop. Usually it is not
necessary to change this setting.
Determined by A1-02
(0.000 - 0.500 s)
If you have a load with low rigidity or if oscillation is a problem, decrease C5-01 in 2-unit decrements or decrease
C5-06 in 0.001-unit decrements.
■
C5-07: ASR Gain Switchover Frequency
No.
(Hex.)
Name Description
Default
(Range)
C5-07
(0221)
ASR Gain Switchover
Frequency
Sets the frequency where the drive will switch between these parameters:
C5-01 and C5-03 [ASR Proportional Gain 1/2]
C5-02 and C5-04 [ASR Integral Time 1/2]
Determined by A1-02
(Determined by A1-02)
Switching the proportional gain and integral time in the low or high speed range can help operation become stable. A
good switching point is 80% of the frequency where oscillation occurs or at 80% of the maximum output frequency.
Note:
An MFDI set for H1-xx = 77 [MFDI Function Selection = ASR Gain (C5-03) Select] will have priority over the ASR gain switching
frequency.
■
C5-08: ASR Integral Limit
No.
(Hex.)
Name Description
Default
(Range)
C5-08
(0222)
ASR Integral Limit
Set the upper limit of the ASR integral amount as a percentage of the rated load.
400%
(0 - 400%)
◆
C6: Carrier Frequency
C6 parameters select the carrier frequency and set the upper and lower limits of carrier frequencies.
■
C6-02: Carrier Frequency Selection
No.
(Hex.)
Name Description
Default
(Range)
C6-02
(0224)
Carrier Frequency Selection
Sets the carrier frequency for the transistors in the drive.
Determined by A1-02 and
o2-04
(Determined by A1-02)
Changes to the switching frequency will decrease audible noise and decrease leakage current.
Note:
When you increase the carrier frequency to more than the default setting, it will automatically decrease the drive current rating.
1 : 2.0 kHz
2 : 5.0 kHz
3 : 8.0 kHz
