Application Examples
Combination with safety components or controllers may be needed for some applications.
Industrial robots
Conveyor line
• By setting a stop area around a robot, the SS1 function can slow
down and stop the robot (once stopped the motor power is shut off)
when a worker enters the area.
• By setting a speed limit area, the SLS function can limit the robot's
operation speed at a safe level while a worker is within the area.
• The STO function can shut off the power of motors without shut-
ting off the conveyor power, enabling workers to safely perform
maintenance and other works. Furthermore, the conveyor opera-
tion can be resumed right away for improved work efficiency.
• The SLS function can limit the machine operation speed at safe
levels, enabling workers to do inspection and setup works with-
out shutting off the conveyor operation.
Functional safety
Broadly compatible with functional safety, enabling easy integration of safety functions in a device.
Functional safety functions defined in IEC/EN 61800-5-2:2016: STO (Safe Torque Off), SS1 (Safe Stop 1), SS2 (Safe Stop 2),
SOS (Safe Operating Stop), SLS (Safely-Limited Speed), SBC (Safe Brake Control), and SSM (Safe Speed Monitor).
