Section C: Tuning Parameters
C5 ASR Tuning
C5-04 ASR Integral Time 2
Setting Range:
Factory Default:
The ASR integral time 2 is an additional integral time adjustment.
C5-05 ASR Output Primary Delay Time
Setting Range:
Factory Default:
Mechanical backlash in an application causes secondary current (I
tions in the motor's rotor. This condition can undesirably limit the adjustment of ASR
parameters. The output delay time constant is used to control these secondary cur-
rent (I ) reference variations.

C5-06 ASR Switching Speed Level
Setting Range:
Factory Default:
Sets speed at which C5-01 and C5-02 are achieved. When C5-06 is set to any set-
ting other than 0, both sets of proportional and integral values are used (See Figure
22).
0
Notes:
1. When C5-06 =" 0", proportional gain 1 (C5-01) and integral time 1 (C5-02) are selected.
C5-07 ASR P Gain at Start
Setting Range:
Factory Default:
This parameter sets the ASR P gain applied at magnetic pole pull-in. It is set to a
unit of 0.01.
