Current Regulator Gains—Manual Adjustment
PowerFlex 755T products allow individual manual adjustment of the
proportional and integral terms that are used by the current regulator. To enable
manual adjustment of the proportional and integral terms, set 13:74 [Cur Reg C/
U Sel] to 1 ‘User Entered’. This setting switches the gains that are used by the
current regulator from the calculated values to values that are entered in
parameters 13:77 [u Cur Reg Kp] and 13:79 [u Cur Reg Ki].
It is recommended to begin manual adjustment with the suggested gain start
points. To initiate the transfer of these values, toggle 13:74 [Cur Reg C/U Sel] to
2 ‘LoadCalcData’. When this option is selected, the calculated gains values are
copied to the user entered gain parameters. When the transfer is complete, 13:54
[Volt Reg C/U Sel] will automatically set to 1 ‘User Entered’ for manual
adjustment.
