External I/O Circuits
Section 3-3
Control I/O Signals
The following table shows the names and functions of the Servo Drive’s con-
trol I/O signals.
CN1 Control Input Signals
CN1 Control Input Signal Connection Diagram
Note
(1) If the limit input signal inputs (Servo Drive's forward drive prohibited sig-
nal and reverse drive prohibited signal) are not allocated, the Servo Drive
will not stop the Servomotor when the signal is input, and the Position
Control Unit will also not detect limit inputs as errors. When using a Posi-
tion Control Unit, always allocate the Servo Drive's forward drive prohib-
ited signal and reverse drive prohibited signal to enable use of the limit
input signals. (Refer to
6-4 Standard Settings for Servo Drives Using
MECHATROLINK
.)
(2) The signal width of the limit input signals (forward drive prohibited signal
and reverse drive prohibited signal) and origin proximity input signal (ori-
gin return deceleration limit switch) must be longer than the MECHA-
Pin No.

12 to 24-VDC Power Supply Input
Power input terminal (12 to 24 VDC) for
sequence inputs.

Immediate stop
This is a general-purpose input.
Functions can be selected by parameters.
Take note that, however, external latch inputs 1
to 3 can only be allocated to IN5 to IN7 (pin
numbers 10 to 12)

BAT
Backup battery input
Backup battery connection terminals when the
absolute encoder power is interrupted.
(Connection to this terminal is not necessary if
you use the absolute encoder battery cable for
backup.)
