Motor control
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
current is measured for earth fault protection.
Printed circuit boards
The drive contains the following printed circuit boards as standard:
• main circuit board (GINT)
• motor control and I/O board (RMIO), 2 pcs
• EMC filter unit (GRFCU) when EMC equipment is selected
• filter boards (GRFC or RRFC)
• varistor board (GVAR)
• control panel (CDP 312R)
• current measurement board (GCUR, in frame size R5 only)
• charging diode board (GDIO).
DDCS communication modules
The drive includes an RDCO-03 module in the line-side converter and another
RDCO module in the motor-side converter.
