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.
7 EDM- This signal outputs the safety stop function (STO) operating status.
 Max. voltage: 30 VDC
8 EDM+
 Max. ON current: 50mA
[EN1+]
*1 EDM output ON/OFF is defined as follows.
ON: Status in which the transistor between the [EDM+] and [EDM-] terminals
is ON
OFF: Status in which the transistor between the [EDM+] and [EDM-]
terminals is OFF
