2.1 I/O connector input signal
Connector
pin No.
(Note 2)
(Note 4)
Connect to the positive or negative
terminal of the external DC source
(12–24 V).
Generates Err 87.0 “Forced alarm
input error”.
Positive direction
over-travel
inhibition input
[Axis A]
12
(SI6)
[Axis B]
2
(SI2)
Positive direction over-travel inhibit
input.
The operation with this input turned
ON is set up in Pr 5.04 "Setup of
over-travel inhibit input".
When using Positive direction
over-travel inhibit input, connect the
signal so that the input is turned ON
when the moving portion of the
machine travels in positive direction
exceeding a limit.
If used as a home position reference
trigger in a home position return, this
input signal should be SI6 for Axis A
and SI2 for Axis B, respectively.
The signal width should be 1 ms or
longer then at the time of closing,
and should be 2 ms or longer then at
the time of opening.
Please keep in mind that it cannot
guarantee this value.
Negative direction
over-travel
inhibition input
[Axis A]
13
(SI7)
[Axis B]
3
(SI3)
Negative direction over-travel inhibit
input.
The operation with this input turned
ON is set up in Pr 5.04 "Setup of
over-travel inhibit input".
When using Negative direction
over-travel inhibit input, connect the
signal so that the input is turned ON
when the moving portion of the
machine travels in negative direction
exceeding a limit.
If used as a home position reference
trigger in a home position return, this
input signal should be SI7 for Axis A
and SI3 for Axis B, respectively.
The signal width should be 1 ms or
longer then at the time of closing,
and should be 2 ms or longer then at
the time of opening.
Please keep in mind that it cannot
guarantee this value.
[Axis A]
11
(SI5)
[Axis B]
1
(SI1)
When using the near home sensor
during the return to home position
operation, input the sensor signal.
If used as a home position reference
trigger in a home position return, this
input signal should be SI5 for Axis A
and SI1 for Axis B, respectively.
The signal width should be 1 ms or
longer then at the time of closing,
and should be 2 ms or longer then at
the time of opening.
Please keep in mind that it cannot
guarantee this value.
