Be sure to install an emergency brake circuit, a protection circuit, an interlock circuit for reverse operation, such as an emergency brake circuit, a protection circuit, a forward and reverse circuit, and an interlock circuit for the upper and lower positioning limits to prevent machine damage, in the external circuit of the programmable controller.
18 -1. When the programmable controller CPU detects abnormal conditions such as WDT errors through self-diagnosis, all outputs are shut off. In addition, when the programmable controller CPU cannot detect abnormalities in the input/output control part, etc., it cannot control the output. At this time, in order to make the machine operate safely, please design the external circuit and mechanism.
