B. Wiring for emergency stop (Motor is not controlled after emergency stop is activated.)
Additional safety module is not required for the wiring in figure 4.8.3. When emergency switch is
activated, STO safety function is enabled. Then, the servo drive stops outputting current to the
motor and the motor will coast to a stop.

C. Wiring for emergency stop (Motor is controlled after emergency stop is activated.)
A safety module with safety time delay function is required when wiring for emergency stop. The
safety module used in figure 4.8.4 is UE410-MU3T5 from SICK. The enabling signal of D1-N
servo drive becomes OFF via Q1 of the safety module. Dec. kill and smooth factor are used in
decelerating the motor. After the safety time delay elapses, Q3 and Q4 of the safety module
send out signals to activate STO safety function. D1-N servo drive stops outputting current to
the motor.
