2.7.3.3 Description of Signals
The signal specifications for the safety device connection connector (CN6) are shown below.
No. Symbol Specification
1 N.C Use is prohibited. Do not wire.
2 N.C Use is prohibited. Do not wire.
3 EN1- This is the [EN1+] input signal common terminal.
4 EN1+ This is the safety stop (STO) input signal.
The servo amplifier will be in the safety stop (STO) condition when input is OFF.

Input voltage: 24 VDC ±10%

Current when ON: 10mA or less

Turn ON/OFF simultaneously with the [EN2+] terminal.
5 EN2- This is the [EN2+] input signal common terminal.
6 EN2+ This is the safety stop (STO) input signal.
The servo amplifier will be in the safety stop (STO) condition when input is OFF.

Input voltage: 24 VDC ±10%

Current when ON: 10mA or less

Turn ON/OFF simultaneously with the [EN1+] terminal.
