AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
Note When you do not use the STO function via safety input signals, short-circuit pins 22 and 23, 24 and 26, 3
and 5, and 6 and 7.
When you use the STO function via safety input signals, remove the attached short-circuit wires and do not
connect anything to pins 7 and 22.
*1. When you use an output signal to drive a relay directly, always insert a diode as shown in the above figure.
Use a high-speed diode.

Pin No. Symbol Name Function and interface
3 and 23 SF1+ Safety input 1 Inputs 1 and 2 for operating the STO function, which are two inde-
pendent circuits. This input turns OFF the power transistor drive
signals in the Servo Drive to cut off the current output to the motor.
