Origin Position Signal Org - Leadshine Technology DMC5400 Hardware Manual

If the PUL/DIR is set to the open collector (Single-ended) output mode, the PUL- and DIR- are used to send out
signals. Please take care that the current sink to PUL- and DIR- pins must not exceed 20mA. The current may
provide by the +5V PUL/DIR power source, and most of motor driver's opto-couplers can work properly when
the current is about 10mA. Have current limiting resistors in series at the PUL&DIR terminals if necessary.

4.2 Origin Position Signal ORG

The origin position signals (ORG0~ORG3) are used as input signals for origin position detecting devices or
mechanisms. The following table lists the relative signal name, pin number, and the axis number.

The input circuits of the ORG signals are shown as Figure 4.2. Usually, a 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 output signals
(PUL/DIR). See "Software Manual for the DMC5400 Motion Controller" for more detail operation of the ORG.
