■ C5-28 M2 ASR Intgl Limit
No.
(Hex.)
Name Description
Default
(Range)
C5-28
(035D)
M2 ASR Intgl Limit
Sets the upper limit for ASR for motor 2 as a percentage of the rated load.
400%
(0 - 400%)
■ C5-29 Speed Ctrl Response Mode
No.
(Hex.)
Name Description
Default
(Range)
C5-29
(0B18)
Expert
Speed Ctrl Response Mode
Sets the level of speed control responsiveness. Usually it is not necessary to change this setting.
0
(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 Perf 1
■ C5-32 M2 I Oper@Ac/Dec
No.
(Hex.)
Name Description
Default
(Range)
C5-32
(0361)
M2 I Oper@Ac/Dec
Sets integral operation during acceleration and deceleration for motor 2.
0
(0, 1)
If you enable integral operation when you are driving a heavy load or a high inertia load, it could cause problems
with overshoot or undershoot at the end of acceleration and deceleration. If there are problems with overshooting
and undershooting, set this parameter to 0.
0 : Disabled
Integral operation is not enabled during acceleration or deceleration. Integral operation is always enabled during
constant speed.
1 : Enabled
Integral operation is always enabled.
■ C5-37 M2 Inertia
No.
(Hex.)
Name Description
Default
(Range)
C5-37
(0278)
Expert
M2 Inertia
Sets the motor inertia for motor 2.
Determined by o2-04 and
C6-01
(0.0001 - 6.0000 kgm
2
)
The drive automatically sets C5-37 to the value of [Motor Inertia] when you do Inertia Tuning or ASR Tuning.
■ C5-38 M2 Inertia Ratio of load
No.
(Hex.)
Name Description
Default
(Range)
C5-38
(0279)
Expert
M2 Inertia Ratio of load
Sets the load inertia ratio for the motor 2 inertia.
1.0
(0.0 - 6000.0)
The drive automatically sets C5-38 to the value of [Load Inertia Ratio] when you do Inertia Tuning or ASR
Tuning.
■ C5-39 ASR Delay Time 2
No.
(Hex.)
Name Description
Default
(Range)
C5-39
(030D)
ASR Delay Time 2
Sets the filter time constant for the time from the speed loop to the torque command output for
motor 2. Usually it is not necessary to change this setting.
0 ms
(0 - 500 ms)
If you have a load with low rigidity or if oscillation is a problem, increase this setting in 0.01 unit increments.
