RDC6432G control system user manual V1.1
The limit polarity is optional. That is, if the motion axis reaches the limit position, a low voltage
signal is triggered to make the LED corresponding limit lights up. And the motion axis leaves the
limit position, a high voltage signal is triggered or the limit signal connection is disconnected to
make When the limit indicator is off, the limit polarity is negative at this time; on the contrary, if
the corresponding indicator is off when the motion axis approaches the limit, and the
corresponding indicator is on when it leaves the limit, the limit polarity is positive. If the limit
polarity is set incorrectly, the limit will not be detected when the system is reset, resulting in axis
collision.
XYU axis limit input port is compatible with 5V/12V/24V logic level input.
4.8 X/Y/U Three-axis drive interface AXIS_X~AXIS_U
The three motion axis interfaces are the same. Take the X axis interface AXIS_X as an example.

The direction signal polarity of the driver can be set. If an axis moves in the opposite direction of
the machine origin when reset, it means that the direction signal polarity of the axis is incorrect.
At this time, the connection between the axis and the motor driver can be disconnected
(otherwise the mainboard cannot detect the limit, which may cause The axis collides), and then
wait until the axis reset is completed, then correct the direction signal polarity of the axis, and
then press the reset button to reset the main board after the modification is completed.
Drive pulse signal may be provided rising or falling edge, default is falling edge.
The pulse signal and direction signal are both OC output, so the controller and
Prompt motor driver must use the common anode connection method. Common
cathode and differential connection methods are not supported.
