Safety Function
Timings of Return from the Safety Status
*1. Make sure that servo ON input is turned OFF when you return the input signals of safety inputs 1 and
2 to ON. Alarm clear must be performed because alarms occurs. Be sure to execute the alarm clear
when both safety inputs 1 and 2 are returned to the ON status. An alarm occurs immediately if the
alarm reset is executed when even one of these is still in the OFF status.
*2. Since this is a status where alarms occurs, the dynamic brake is based on the Stop Selection for
Alarm Detection (Pn510).
*3. Since this is a normal servo OFF status, the dynamic brake is based on the Stop Selection with Servo
OFF (Pn506) setting.
