Title:
METHOD FOR JUDGING COMMUNICATION STATE IN A CONTROL SYSTEM OF LINKED JOINTS
Document Type and Number:
WIPO Patent Application WO/2003/015996
Kind Code:
A1
Abstract:
A method for judging whether the communication state between a main control unit and a sub control unit is normal or abnormal when a noise may be generated from a drive system conductor. The method comprises a power supply step s4, a test communication step (see arrows (3), (4)), and a judgment step s6. In the power supply step s4, power is supplied to a first sub control unit (2a) from a drive system power source (6) while no power is supplied to an actuator (7) from the power source (6). In the test communication step, a test signal is communicated between the main control unit (1) and the sub control unit (2). In the judgment step s6, the communication state is judged to be normal or abnormal in accordance with the communication result of the test signal between the main control unit (1) and the sub control unit (2).
