Parameter Details
5
n 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 C5-05: ASR Limit on page 149.
n
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 C5-06:
ASR Primary Delay Time Constant on page 149.
Note: This parameter rarely requires adjustment.
n 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 C5-01, C5-03 / C5-02, C5-04: ASR Proportional Gain 1, 2 / ASR Integral Time
1, 2 on page 148.
Note: A multi-function input set for the ASR gain switch (H1- = 77) takes priority over the ASR gain switching frequency.
n 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.
n
C5-32: Integral Operation during Accel/Decel for Motor 2
Functions for motor 2 in the same way that C5-12 functions for motor 1.
Enables integral operation during acceleration and deceleration. For more details, see C5-12: Integral Operation during
Accel/Decel (V/f w/PG) on page 150.
Setting 0: Disabled
Integral operation occurs only during constant speed and not during acceleration or deceleration.
Setting 1: Enabled
Integral operation is always enabled.
n
C5-37, C5-38: Motor 2 Inertia, Motor 2 Load Inertia Ratio
These parameters function for motor 2 in the same way that C5-17 and C5-18 function for motor 1.
