2 SAFETY OBSERVATION FUNCTION
Item
External sensor input X
device No.
(1) Speed monitoring parameter
Set the input (X) device No. on the PLC CPU side (occupies two points) of the
safety signal module which inputs pulses of the pulse output system connected
mechanically to the servo axis performing speed monitor.
In the Motion CPU side, the input (X) device number corresponding to the input
(X) device number set on the PLC CPU side is assigned. Make sure to set the
A-phase/B-phase mode to use the standstill monitoring (SOS).
[Setting device number is an even number. (A-phase/B-phase mode)]
• External auxiliary pulse input A-phase: X (setting device No.)
• External auxiliary pulse input B-phase: X (setting device No. + 1)
[Setting device number is an odd number. (1-phase mode)]
• External auxiliary pulse input: X (Setting device No.)
("Setting device number -1" can be used as a general input.)

X200 Unused (Usable as a general input.)
X201 Sensor input for block No.1 (1-phase)
X202 Sensor input for block No.2 (A-phase)
X203 Sensor input for block No.2 (B-phase)
X204 Unused (Usable as a general input.)
X205 Sensor input for block No.3 (1-phase)
When 1FFF is set, external auxiliary pulse input is disabled only if "Number of
pulses per external sensor rotation" and "Movement amount per external sensor
rotation" are 2147483647.
