Input
EA
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 7.)
Input pulse: 32 kHz
max.
Internal resistance:
10 k
Voltage between this
input terminal and the
terminal L:
5 to 24 VDC
ON voltage: 4V min.
OFF voltage: 1V max.
Allowable voltage:
27 VDC max.
7
(EB)
Pulse input -
B
Set the Multi-function Input 7
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 EA.)
Input pulse: 32 kHz
max.
Internal resistance:
4.7 k
ON voltage: 18 V min.
OFF voltage: 3 V
max.
Allowable voltage:
27 VDC max.
Load current: 5 mA
(at 24 V)

Multi-func-
tion output
Select two functions from among
47 functions, and allocate them
to terminals 11 and 12. These
terminals support both the sink
logic and the source logic. For
details on the connection, refer to
Multi-function Output Terminals
and Programmable Controller
Connection on page 2-40.
Open collector output
Between each termi-
nal and CM2
Allowable voltage:
27 V max.
Allowable current:
50 mA max.
Voltage drop at
power-on: 4 V max.

(EDM)
Safety moni-
tor
Turn ON the EDM function selec-
tor switch to enable this terminal.
This automatically sets this termi-
nal to 11 (EDM: Safety monitor
signal).
CM2
Output sig-
nal common
Common terminal for multi-func-
tion output terminals 11 and 12.
Allowable current:
100 mA max.
