ASR Primary Delay
Time Constant 2
ASR Delay Time 2
Sets the filter time constant in seconds for the time from the
speed loop to the torque reference output when the Power KEB
Ride-Thru is enabled (L2-29 = 1).
Note: This parameter is not available in models
4A0930 and 4A1200.
Default: 0.000 s
Min.: 0.000
Max.: 0.500

<1> Default setting is determined by parameter A1-02, Control Method Selection.
<2>
The setting range is 1.00 to 300.00 in CLV and AOLV/PM control modes.
<3> Default setting is dependent on parameter E5-01, Motor Code Selection.
<4> Default setting is dependent on parameters C6-01, Drive Duty Selection, and o2-04, Drive Model Selection.
<5> Default setting is determined by parameter E3-01, Motor 2 Control Mode Selection.
