Setting Range: 0.000 to 10.000s

Factory Default: 0.500s

The ASR integral time 2 is an additional integral time adjustment.

Sets ASR frequency compensation limit as a percentage of maximum output frequency (El -04). This

function is enabled when V/f control with PG feedback is selected as the control method (A1-02).

Setting Range: 0.000 to 0.500s

Factory Default: 0.004s

Mechanical backlash in an application causes secondary current (I

) reference variations in the motor’s

rotor. This condition can prevent the adjustment of ASR parameters.The output delay time constant is

used to control these secondary current (I

) reference variations.

Setting Range: 0.0 to 400.0Hz

Factory Default: 0.0Hz

Sets frequency to change ASR proportional gain and integral time constant in units of 0.1Hz when flux

vector control is selected.

Notes:

1.When C5-07 =”0”, proportional gain 1 (C5-01) and integral time 1 (C5-02) are selected.

2.During V/f control with PG feedback (A1-02 = “1”), the frequency switching level becomes

the maximum output frequency (E1-04).
