System Overview

A muti-winding drive system consists of a multi-winding drive unit, SERVOPACKs,
converters, and a multi-winding servomotor.
The functions of these devices are described below.
• Multi-Winding Drive Unit
• The multi-winding drive unit supports either analog voltage/pulse train references
or MECHATROLINK-II communications references for the host controller inter-
face.
• The multi-winding drive unit is connected to the encoder of a multi-winding servo-
motor and it performs position, speed, or torque control.
• The multi-winding drive unit is connected to SERVOPACKs with local communi-
cations cables and it controls the SERVOPACKs.
• SERVOPACKs and Converters
• The servomotor is driven with references from the multi-winding drive unit.
• The correct capacities and numbers of SERVOPACKs and converters must be pre-
pared for the capacity of the multi-winding servomotor.
• Multi-Winding Servomotor
• The multi-winding servomotor has more than one set of main circuit terminals
because it is driven by more than one SERVOPACK.
