5.5 Current Loop
CURRENT LOOP:
In "
Current Loop
" it is possible to modify the dynamic constants of the drive’s current loop:
I rms:
In this box it is possible to insert the percentage value of the rated current furnished by the
drive. The numerical range is between 1 and 50 and it is referred to the peak current value.
Example: suppose we have a drive size 8/16, if we insert into this box the value 15%, we’ll have a
setting of rated current equal to 2,4A (in fact 16X15/100=2,4), so the drive will provide a rated cur-
rent equal to 2,4A to the motor.
I peak:
In this section it is possible to insert the percentage value of the peak current furnished by
the drive. The numerical range is between 1 and 100
Example: suppose we have a drive size 8/16, if we insert into this box the value 75%, we’ll have a
setting of peak current equal to 12A (in fact 16X75/100=12), so the drive will provide a peak current
equal to 12A to the motor.
The value of nominal and peak current is RMS.
I2T:
Time of the peak current.
Typically with an adjustment of Ipeak = 100%, the time will be 5 seconds.
KP:
It is the proportional gain of the current loop. This adjustment allows for optimizing the dynamic
behaviour of the motor’s current loop. The numerical range of this parameter varies from 0 up to 999.
Ti:
It is the integral time in “ms” of the current loop.
The numerical range of this parameter varies from 0 up to 999ms.
