RDC644XG Controller User Manual

The pin definitions of Z/U axis limit input CN3 are the same as CN4.

X/Y/Z/U-axis limit inputs are compatible to 5V/12V/24V logic level inputs.

4.9 X/Y/Z/U-axis Motor Driver Interface AXIS_X~AXIS_U

The interfaces of the four motion axis are the same. The AXIS-X interface is exampled.

The polarity of directional signal for driver pulse signal can be set. Where a certain axis is reset, it

will move to the opposite direction of machine origin, which means the polarity of directional

signal for this axis is not correct. In such a case, the connection between this axis and the motor

driver can be broken first (otherwise the controller cannot be detected to the limit so as to lead to

the collision of this axis), and then such a polarity can be corrected after this axis is reset

completely. Upon the correction, the reset key can be pressed against to reset the controller.

And, the pulse signal can be falling edge valid or rising edge valid. The default setting is falling

edge valid.

Prompt

The Pulse signal and the directional signal are all OC outputs. The Controller

must be common anode with the motor driver

4.10 Laser Power Control Interface CN5/CN6

This control system has two independent and adjustable digital laser power control interfaces.

Signals of the two interfaces are similar and the first digital interface (CN5) is hereby example:

Laser-enabled control interface

1. When the laser is the RF laser, this pin will not be used;

2. When the laser is a glass tube, if the used laser is outputted in

the low-level form, this pin will be connected with the laser

power enable end and used to control the ON/Off of laser.
