3.3 Origin Signal ORG
The origin signals (ORG1-ORG4) are used as input signals for the
origin of the mechanism. The table below lists signal names, pin
numbers, and axis numbers.
The input circuit of the ORG signals is shown below. Usually, a
limit switch is used to indicate the origin on one axis. The specifi-
cations of the limit switch should have contact capacity of +24 V @
6 mA minimum. An internal filter circuit is used to filter out any high
frequency spikes, which may cause errors in the operation.
When the motion controller is operated in the home return mode,
the ORG signal is used to inhibit the control output signals (OUT
and DIR). For detailed operations of the ORG signal, refer to sec-
tion 4.3.3.
