Stop Circuit
Note 1 It is not equipped with a relay that automatically identifies that a teaching tool was
inserted and switches over the wiring layout. Connect a dummy plug to the SIO
connector in normal operations.
Note 2 Construct the circuit considering the safety category of the whole equipment.
Note 3 Make sure to construct the emergency stop circuit using the built-in 24V (EMG+
Terminal) output for EMG- Terminal.
Note 4 As it is not equipped with the built-in motor drive cutoff relay, it is necessary to establish
external drive cutoff.
For the SDN terminal (Drive cutoff contact output)
SDN1, SDN2
•
It is the contact output to control the drive cutoff device connected externally.
•
Configure the circuit in such a way that the drive source will never be turned
on when these contacts are open.
When turning on the power, turn on the control power first, confirm that these
contacts are closed, and then turn on the drive power.
•
The rating of this contact is 30V max. / 200mA max.
Conditions to Open SDN Contact
1) At stop signal input (when the dry contact connected between EMG+ and EMG- is open)
2) When an alarm is generated (Cold start level)
3) In disable condition
