Signal Arrangement and Electrical Specifications
The signal arrangement of the emergency stop input connector is shown in the following table.
| Pin Number | Signal Name | Function |
|---|---|---|
| 1 | 24V for emergency stop | Internal 24V output |
| 2 | Emergency stop input M *1 | Emergency input 1 |
| 3 | N.C. *2 | Not used |
| 4 | 24V for emergency stop | Internal 24V output |
| 5 | Emergency stop input S *1 | Emergency input 2 |
| 6 | N.C. *2 | Not used |
| 7 | N.C. *2 | Not used |
| 8 | N.C. *2 | Not used |
*1 An error occurs if the input times of emergency stop input M and emergency stop input S differ by two seconds or more. Connect a switch having two identical contacts.
*2 Do not connect anything to these pins.
Electrical characteristics of EMERGENCY connector
- 24V rated load for emergency stop: +24 V 0.4 A or less
- Emergency stop input voltage range: +24 V ±10%
- Emergency stop input current: 37.5 mA ±10% at +24 V input
CAUTION
- The 24 V output for emergency stop is for connecting to emergency stop switches, relays, MOS-FETs, and other switches. Do not use it for other purposes. Doing so may result in system breakdown.
KEY POINTS
The total electrical resistance of the emergency stop switches and their circuit should not exceed 1 Ω.
WARNING
Cables should be connected at all times. Use a guard cover to protect the cables. Do not put heavy objects on the cables, bend or pull on the cables forcibly, or allow the cables to be pinched. Damaged cables, broken wires, or contact failure is extremely hazardous and may result in electric shock and/or malfunction of the robot system.
