Wiring Example
Wiring Example When EDM is Used (Conforming to PLd under ISO13849-1)
Safety input
Safety switch
(The figure shows
an emergency-stop
pushbutton switch.)
When the emergency stop button is pressed, the current flowing through GS1 and GS2 is cut
off and the Inverter output is cut off. As a result, the motor enters a free-run status. This
operation corresponds to stop category 0 under IEC60204-1.
Note 1. Shown above are wirings that apply when the multi-function input terminals are used based on
the source logic. If they are used based on the sink logic, the wiring must be changed. For details,
refer to "Connection to Programmable Controller (PLC)" on page 2-22.
Note 2. The safety relay and emergency shutoff input signal line must use a shielded coaxial cable such
as RG174/U (by LAPP) per MIL-C17 or KX3B per NF C 93-550 with an outer diameter of 2.8 mm
and length of 20 m or less. Ground the shield.
Note 3. All inductor parts such as relays and contactors must have an overvoltage protection circuit.
