Description
Each terminal function
can be selected by
parameter setting for
each terminal.
Both sink logic and
source logic are
supported. See "5.4.3
Switching Sink/Source
Logic and Connecting
External Power Supply/
Programmable Controller"
for more information.
Common terminal for
output terminal [11] and
[12].
1c contact output.
Terminal function can be
selected by parameter
setting.
(The default setting is
alarm output.)
The monitor value
selected by the
parameter is output as a
pulse signal or PWM
signal. Adjustable with
[C030], [C047] and
[C105].
RS485 ports for Modbus-
RTU/EzCOM.
Maximum baud
rate :115.2 kbps
To connect the signal
ground of the external
control device, use [L]
terminal.
24 VDC power supply
terminal dedicated to
[ST1]/[ST2] terminals.
Common terminal for
[P24S].
STO input terminal.
Refer to "14.1 Using the
Safety Function STO (Safe
Torque Off)" for more
information.
When EDM function
switch is turned on,
output terminal 11
switches to the EDM
output signal. Refer to
"14.1 Using the Safety
Function STO (Safe
Torque Off)" for more
information.
