Title:
MOTOR CONTROL SYSTEM, MOTOR CONTROL DEVICE, PROGRAM AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2017/158944
Kind Code:
A1
Abstract:
The present invention enables mutual relationships among operation statuses of each motor to be ascertained without using synchronous serial communication between multiple motor control devices. The motor control system (100) is equipped with: a motor driver (30a) having a trigger determination unit (34) for determining whether or not a trigger condition is satisfied, a trigger notification unit (36) for transmitting a trigger notification indicating that the trigger condition is satisfied to motor drivers (30b, 30c) by means of asynchronous communication, and a tracing result information generation unit (35) for causing a storage unit (39) to store a trigger data number for identifying operation data when the trigger condition is satisfied; and motor drivers (30b, 30c) each having a tracing result information generation unit (51) for causing storage unit (55) to store a slave trigger time (t2) at which the trigger notification is received, a trigger data number for identifying operation data corresponding to the slave trigger time (t2), and a master trigger time (t1).
