Digital Power supply SC Input signal
common Common terminal for the internal
power supply, digital input, and
analog I/O terminals.
P24 Input signal
power sup-
ply This is 24-VDC power supply for
contact input signal. For source
logic input, this terminal functions
as the common terminal. Allowable current:
100 mA max.
PSC Input termi-
nal power
supply For sink logic input: Short-cir-
cuited to P24
For source logic input: Short-cir-
cuited to SC
To activate contact input via an
external power supply, remove
the short-circuit bar. For details
on the connection, refer to
Multi-function Input Terminals
and Programmable Controller

Multi-
function
input Select seven functions from
among 68 functions, and allocate
them to terminals S1 to S7.
These terminals support both the
sink logic and the source logic.

(GS2) Safety input Turn ON the safety function
selector switch to enable this ter-
minal. This automatically config-
ures S3 and S4 as follows.
S3: GS1 (Safety input 1)
S4: GS2 (Safety input 2)
Pulse RP Pulse input -
A This is pulse input for frequency
setting. This terminal accepts 5
to 24 VDC input signals. (Note
that this terminal is connected to
a different internal circuit from
the input terminal S7.) Input pulse: 32 kHz
max.
Internal resistance:
10 k
Ω
Voltage between this
input terminal and the
terminal SC:
5 to 24 VDC
ON voltage: 4V min.
OFF voltage: 1V max.
Allowable voltage:
27 VDC max.
S7
(EB) Pulse input -
B Set the Multi-function Input S7
Selection (C007) to 85 (EB:
Rotation direction detection) to
enable this terminal. This is pulse
input for frequency setting. (Note
that this terminal is connected to
a different internal circuit from
the input terminal RP.) Input pulse: 1.8 kHz
max.
Internal resistance:
4.7 k
