Mode

Displays the power structure used in the drive. This is an identifier to the firmware for power structure control.
Bit 0 “Lo Pwr Strct” = PowerFlex 700S Frame 1 to 6
Bit 1 “Hi Pwr Strct” = PowerFlex 700S above Frame 6
Bit 3 “Parallel Drv” = PowerFlex 700S Frame 12
Note: Bit 3 “Parallel Drv” was added for firmware version 3.001.

Iqs Integ Freq

Sets the break frequency of the torque producing (q-axis) current regulator. This and
