The Modular Servo Control System is a high power control chassis used to drive up to 8 linear variable reluctance motors. The chassis includes cooling fans, and a control signals distribution board for easy connection to the machine controller. Space is provided for the system power supply and the chassis is shipped with power distribution wiring in place.

The system is modular since it is designed to serve machines that have 3, 4, 6 or 8 axes. The servo drives are independent of each other. They perform current control of the motor’s three independent phases, and receive a commutated analog current command from the machine controller.
