CfgCurrentControl
iCtrlPropGain
iCtrlIntGain
The parameter object CfgCurrentControl is not required for:
Virtual axes (MP_axisMode = Virtual)
Axes that are only for display (MP_axisMode = Display)
Analog axes (MP_axisHw = AnalogMC, AnalogCC)
Several digital current controllers for the axes and spindle(s) are integrated in
the MANUALplus 620.
The nominal values for magnetizing current I
divided into the PWM signals U
rotator VD+, and are transferred to the power module through X51 to X60 (via
internal connections on the UEC 11x).
The actual current values I
and are transferred to vector rotator VD– through X51 to X60 (via internal
connections on the UEC 11x). The vector rotator determines the actual values
of magnetizing current I
