ELECTRIC INVERTER,S ASR LIMIT AND ASR PRIMARY DELAY TIME,SWITCHING FREQUENCY.




ASR LIMIT.

the upper limit of compensation frequency of speed control . it is in unit of% with maximum frequency taken as 100%.

NOTE:

since c 5-0 5 can,t be changed during operation stop the inverter,s operation and then decrease the asr limit by 0.5(%). perform step 3 again after the setting has been changed.the asr limit is the frequency limit for compensation by the maximum output frequency if the frequency limit is lowered too much the motor speed might not reach the target speed. verify that the target speed is reached during normal operation.

ASR PRIMARY DELAY TIME.

it is the delay time when the torque is output from speed control circuit . it is in unit of second.

NOTE:

no need to changed morally .constant c 5-0 6 can be used when adjusting the gain dose not remove motor oscillation , or adjusting the gain removes oscillation but result in poor responsiveness. a high c 5-0 6 setting lowers the responsiveness of the speed control , but makes it difficult for oscillation to occur.

ASR SWITCHING FREQUENCY.

sets the frequency for switching between proportional gain 1,2 and integral time 1,2  in H z units

NOTE:

it is used to set the switching frequency of asr proportional gain / integral time.
