  Signal judgment 
Signal terminal 
Used to emergency-stop the robot from the external 
equipment. 
While this signal is open, the processing of robot emergency 
stop is executed. 
Use this signal by connecting a safety device such as safety 
door switch, photoelectric type sensing safety device and 
safety mat switch. 
When the emergency stop input contact is open, emergency 
stop contact output is short-circuited between SAD-COM* 
and SAD-*a. 
Safety door contact output is c-contact. Use this signal in 
accordance with the customer’s specifications.

1.  While this signal is open, the servo power cannot be 
turned on in any mode. 
2.  SAD-IN* to SAD-OUT* are assumed to have two (2) b 
contacts interconnected, which should be turned on and 
off at the same time. If there is a delay in contact input 
operation, the non-conformity detection function of 
hardware works to retain emergency stop. 
If error clear is not done even after emergency stop 
latch input, confirm whether this signal has two (2) b 
inputs interconnected. 
3.  Unless this signal is used, short-circuit SAFE-13 to 
SAFE-14 and SAFE-15 to SAFE-16.
