The ACQ800-37
Motor-side converter
The motor control is based on the Direct Torque Control (DTC) method. Two phase
currents and DC link voltage are measured and used for the control. The third phase
control is measured for earth fault (ground fault) protection.
Frame R6
The motor-side converter is controlled by an RDCU drive control unit located in the
integrated line-side/converter-side module.
Frame R7 and up
The motor-side converter is controlled by an RDCU drive control unit located in the
swing-out frame of the cabinet. The RDCU is connected to the inverter module(s) by
a fiber optic link, distributed through an optical branching unit. In the inverter
modules, the optic link connects to the AINT board, the terminals of which are
accessible through a hole on the front panel of the module.
