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
Note 2. The safety relay and emergency shutoff input signal line must use a shielded coaxial cable such
Note 3. All inductor parts such as relays and contactors must have an overvoltage protection circuit.
