Origin Signal ORG

The origin signals (ORG1-ORG4) are used as input signals for the
origin of the mechanism. The following table 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 +24V @
10mA 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 (CW
and CCW). For detailed operations of the ORG signal, refer to
Section 4.
