2 SYSTEM CONFIGURATION
(4) Wiring example for the safety signal module
(a) Wiring example for door signal to safety signal module and AC contactor.
Wiring example to shut off contactor by the followings is shown 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
• Contactor shut-off output MC1 and MC2 of servo amplifier
Input the output signal of auxiliary normally closed contact into the safety
signal module to detect the weld of contactor.
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.
