Document Type and Number:
WIPO Patent Application WO/2023/067893
Kind Code:
A1
Abstract:
The present invention prevents an erroneous operation caused by an inappropriate control program. A serve control device (10) comprises: a control unit (20) that controls a target device in accordance with a control program; and a power source unit (30) that supplies power to the control unit (20). The control unit (20) includes a first output terminal (21) that outputs a first signal if an appropriate control program is written, and outputs a second signal if an inappropriate control program is written. The servo control device (10) further comprises an input/output circuit (40) that, in the case that the second signal has been output from the first output terminal (21), receives the second signal and outputs an error signal. The control unit (20) further includes an input terminal (22) into which an output signal from the input/output terminal (40) is input. The control unit is configured to inhibit the control of the target device if the error signal has been input into the input terminal (22).
