[Caution] The emergency stop input(terminal block) on the user wiring in the controller can be used for safety
measures as shown in
cable length, so refer to the following and install.
・ Switch contact .......................................... In the case of CR2B-574/CR3-535M controller, prepare a 2-
・ Switch contact capacity........................ Use a contact that operates with a switch contact capacity of
・ Cable length................................................ The length of the wire between the switch and terminal block
・ Emergency stop output capacity....... Set it within 300 mA/24 VDC.
[Reference] The specifications of the RA1 and RA2 coil shown in
・ Rated voltage ............................ DC24V ± 10％
・ Rated excitation current ...... 12.5mA ± 10％ （at25 deg.）
* Note that these specifications are subject to change without prior notice for modification purposes.
The emergency stop circuit in the robot is a duplex type to ensure safety(CR2B-574 controller only).
Thus, if a 1b contact type is used, faults such as fusing in the emergency stop circuit will not be detected, and
could lead to fires.
If a 1b contact type is used and the emergency stop is input with only one side (across No. 1-2 or No. 5-6), the
contact fusing alarm will occur, and resetting of the alarm will not be possible.

contact type.

must be max. 15m or less.
Connecting an external device outside of the above range will
cause a controller failure.
