■ C5-32: Motor 2 Integral Oper at Acc/Dec
No.
(Hex.)
Name Description
Default
(Range)
C5-32
(0361)
Motor 2 Integral
Oper at Acc/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: Motor 2 Inertia
No.
(Hex.)
Name Description

Motor 2 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: Motor 2 Load Inertia Ratio
No.
(Hex.)
Name Description

(Range)
C5-38
(0279)
Expert
Motor 2 Load Inertia
Ratio
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 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 for the time from the speed loop to the torque
command output for motor 2. Usually it is not necessary to change this
setting.
0.000 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.
■ C5-50: Notch Filter Frequency
No.
(Hex.)
Name Description
Default
(Range)
C5-50
(0B14)
Expert
Notch Filter
Frequency
Sets the machine resonance frequency.
0 Hz
(0, or 2 to 100 Hz)
Machine resonance can cause high-frequency noise and vibration during operation. A notch filter can help prevent
the noise and vibration. Notch filters set the resonant frequency of the machine to remove specific vibrational
frequency components caused by machine resonance.
