C5-17, C5-18: Motor Inertia, Load Inertia Ratio
C5-17 and C5-18 determine the ratio of the machine inertia and the inertia of the motor being used.
These parameters are set automatically when Inertia Tuning and ASR Tuning are performed in CLV and CLV/PM control
modes. Refer to Auto-Tuning on page 100 for details on Auto-Tuning or enter the data manually.

C5-21, C5-23 / C5-22, C5-24: Motor 2 ASR Proportional Gain 1, 2 / Integral Time 1, 2
These parameters function for motor 2 the same way that C5-01 through C5-04 function for motor 1. Refer to C5-01, C5-03/
C5-02, C5-04: ASR Proportional Gain 1, 2/ASR Integral Time 1, 2 on page 163 for details.
No. Parameter Name Setting Range Default
C5-21 Motor 2 ASR Proportional Gain 1 0.00 to 300.00 Determined by E3-01
C5-22 Motor 2 ASR Integral Time 1 0.000 to 10.000 s Determined by E3-01
C5-23 Motor 2 ASR Proportional Gain 2 0.00 to 300.00 Determined by E3-01
C5-24 Motor 2 ASR Integral Time 2 0.000 to 10.000 s Determined by E3-01
n
C5-25: Motor 2 ASR Limit
Functions for motor 2 the same way that C5-05 functions for motor 1. Sets the ASR output limit for motor 2 as a percentage
of the maximum output frequency (E4-04). Refer to C5-05: ASR Limit on page 164 for details.
No. Parameter Name Setting Range Default
C5-25 Motor 2 ASR Limit 0.0 to 20.0% 5.0%
n
C5-26: Motor 2 ASR Primary Delay Time Constant
Functions for motor 2 the same way that C5-06 functions for motor 1.Sets the filter time constant for the time from the speed
loop to the torque command output. Refer to C5-06: ASR Primary Delay Time Constant on page 164 for details. This
parameter rarely needs to be changed.
No. Parameter Name Setting Range Default
C5-26 Motor 2 ASR Primary Delay Time Constant 0.000 to 0.500 s 0.004 s
n
C5-27: Motor 2 ASR Gain Switching Frequency
Functions for motor 2 the same way that C5-07 functions for motor 1. Sets the frequency for motor 2 to change ASR proportional
gain 1 and 2 (C5-21, C5-23) as well as the integral time 1 and 2 (C5-22, C5-24). Refer to C5-01, C5-03/C5-02, C5-04: ASR
Proportional Gain 1, 2/ASR Integral Time 1, 2 on page 163 for details.
No. Parameter Name Setting Range Default
C5-27 Motor 2 ASR Gain Switching Frequency 0.0 to 400.0 Hz 0.0 Hz
Note:
A multi-function input set for the ASR gain switch (H1-oo = 77) takes priority over the ASR gain switching frequency.
n
C5-28: Motor 2 ASR Integral Limit
Functions for motor 2 the same way that C5-08 functions for motor 1. Sets the upper limit for ASR as a percentage of the rated
load. Refer to C5-08: ASR Integral Limit on page 164 for details.
No. Parameter Name Setting Range Default
C5-28 Motor 2 ASR Integral Limit 0 to 400% 400%
n
C5-32: Integral Operation during Accel/Decel for Motor 2
Functions for motor 2 the same way that C5-12 functions for motor 1. Enables integral operation during acceleration and
deceleration. Refer to C5-12: Integral Operation during Accel/Decel (V/f w/PG) on page 164 for details.
No. Parameter Name Setting Range Default
C5-32 Integral Operation during Accel/Decel for Motor 2 0, 1 0
