Setting Range:
0.000 to 10.000s
Factory Default:
0.500s
The ASR integral time 2 is an additional integral time adjustment.
Setting Range:
0.000 to 0.500s
Factory Default:
0.004s
Mechanical backlash in an application causes secondary current (I
2
) reference varia-
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
2
) reference variations.
Setting Range:
0.00 to 100.00%
Factory Default:
0.00%
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).

5.00
This parameter sets the ASR P gain applied at magnetic pole pull-in. It is set to a
unit of 0.01.
