*1 Do not connect anything to these pins.
*2 An error occurs if the timing of the input of safeguard input 1 and safeguard input 2 differ by two seconds or more. Connect a switch having two identical contacts.
*3 An error occurs if the timing of the input of the emergency stop switch input 1 and emergency stop switch input 2 differ by two seconds or more. Connect a switch having two identical contacts.
*4 Do not apply reverse voltage to the emergency stop input circuit.
| Circuit | Voltage | Pin |
|---|---|---|
| Emergency stop switch output rated load | +30 V 0.3 A or under | 1-2, 14-15 pin |
Safeguard input voltage range Safeguard input current | +24V ±10% 10 mA / +24V input | 7-8, 20-21 pin |
Latch release input voltage range Latch release input current | +24V±10% 10 mA / +24V input | 18-19 pin |
CAUTION
- The 24 V output is for emergency stop. Do not use it for other purposes. Doing so may result in system breakdown.
- Do not apply reverse voltage to the emergency stop circuit. 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.
