Notice that the alternative name means that if users don’t use motion
functions at one or more axes, the digital input will be treated as general
purpose input channel.
The input circuits of the ORG signals are shown as following. Usually, a limit
switch is used to indicate the origin of one axis. The specifications of the limit
switches should with contact capacity of +24V, 6mA minimum. An internal
filter circuit is used to filter out the high frequency spike, which may cause
wrong operation.

When the motion controller is operated at the home return mode, the ORG
signal is used to stop the control output signals (OUT and DIR) a utomatically.
