MULTISPINDLE CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a multispindle control system strong against external noise in which synchronous control can be carried out with high accuracy at low cost and a more flexible arrangement can be realized. SOLUTION: A plurality of driver control cards delivering PWM signals as respective drive control signals to a power control section supplying a drive voltage to a plurality of motors, and a host controller circuit connected with the driver control cards through a bus line are arranged on a bus board and a differential signal is used as a PWM signal from the driver control card.
