
C5-17, C5-18: Motor Inertia, Load Inertia Ratio
C5-17 and C5-18 determine the ratio of the machine inertia to the inertia of the motor being used.
Example: Setting C5-18 to 2.0 reflects a load inertia that is twice the motor inertia.
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 120


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 in the same way that C5-01 through C5-04 function for motor 1. For more details,
see C5-01, C5-03/C5-02, C5-04: ASR Proportional Gain 1, 2 / ASR Integral Time 1, 2 on page


C5-25: Motor 2 ASR Limit
Functions for motor 2 in 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). For more details, see
No.
C5-25

C5-26: Motor 2 ASR Primary Delay Time Constant
Functions for motor 2 in 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. For more details, see
ASR Primary Delay Time Constant on page
Note: This parameter rarely requires adjustment.
No.
C5-26

C5-27: Motor 2 ASR Gain Switching Frequency
Functions for motor 2 in 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). For more details, see
1, 2 on page 192.
No.
C5-27
Note: A multi-function input set for the ASR gain switch (H1- = 77) takes priority over the ASR gain switching frequency.

C5-28: Motor 2 ASR Integral Limit
Functions for motor 2 in the same way that C5-08 functions for motor 1.
Sets the upper limit for ASR as a percentage of the rated load.
