2 SYSTEM CONFIGURATION
(b) Wiring example for door signal to safety signal module and STO terminal.
Wiring example to wire the following methods are shown in the diagram
below.
• Shut-off signal from the Motion CPU side of safety signal module
• Shut-off signal from the PLC CPU side of safety signal module
• STO terminal of servo amplifier
Door sensor used as a safety signal should have two outputs and is wired to
both Motion CPU side and PLC CPU side. Sensor and switch used as
safety signal should be the ones for weak signal use (e.g. twin contact) to
prevent contact failure.
