<P>PROBLEM TO BE SOLVED: To provide a motor control system that allows synchronous control to be easily performed and the setting of a master and a slave to be done, by merely connecting two servo amplifiers with a communication cable. <P>SOLUTION: The servo amplifier 1 (2) has an encoder communication cable 5 (6) for a driven servomotor 3 (4), connected at one two-way communication means 15 (26), and the communication cable 7, connected from another two-way communication means 16 to a two-way communication means 25. A device control part 11 (21) selectively connects the two-way communication means 15 (25) to an inter-device communication part 13 (23) or encoder communication part 12 (22) via a selector 4 (24) by a selector switching signal 11d (21d) output, at the start of communication and automatically determines a master or slave in synchronous control. <P>COPYRIGHT: (C)2010,JPO&INPIT |
