Safety stop signal Common terminal *1 Sink logic is initially set for the FM-type inverter. *2 Source logic is initially set for the CA-type inverter. 72 2. INSTALLATION AND WIRING 2.6 Control circuit Terminal symbol Common Terminal name Terminal function description Rated specification Refer to page S1 SIC Safety stop input (channel 1) Use terminals S1 and S2 to receive the safety stop signal input from the safety relay module. Terminals S1 and S2 can be used at a time (dual channel). The Inverter judges the condition of the internal safety circuit from the status (shorted/opened) between terminals S1 and SIC, or between S2 and SIC.
When the status is opened, the inverter output is shut off. In the initial status, terminal S1 and S2 are shorted with terminal PC by shorting wires. Terminal SIC is shorted with terminal SD. Remove the shorting wires and connect the safety relay module when using the safety stop function. Input resistance: 4.7 kΩ, input current: 4 to 6 mADC (with 24 VDC input) 83 S2 Safety stop input (channel 2) So (SO) SOC Safety monitor output (open collector output) The output status varies depending on the input status of the safety stop signals. The output is in HIGH state during occurrence of the internal safety circuit failure. The output is in LOW state otherwise.
(The open collector transistor is ON (conductive) in LOW state. The transistor is OFF (not conductive) in HIGH state.) Refer to the Safety Stop Function Instruction Manual (BCN-A23228-001(E)) if the output becomes in HIGH state even though both terminals S1 and S2 are open. (Contact your sales representative for this manual.) Permissible load: 24 VDC (27 VDC at maximum), 0.1 A (The voltage drop is 3.4 V at maximum while the signal is ON.)
