4. Description of Interface Signal for IO Board
4.1 Interface of Main Power Source CN1
This control system employs single 24 power supply. For a certain margin, it is
suggested to select 24V/2A power. Besides, this system is compatible with 36V
power, that is to say, the 36V power of Motion driver can directly be connected to
this main power port of this system, but generally it is not suggested to do so.
4.2 Panel Signal-Cable Interface HMI
HMI is a standard DB9 port, with the special cable shipped with the controller, may
connect the IO board and the panel.

General output 1. When the blower control is enabled, this port will
output the control signal of the blower, otherwise it will output other
special control signals. When the blower is connected and its control
enabled, the blower switch can be set separately on each layer. If the
relay is connected externally, the relay coil will be broken over when
the blower is on; the relay coil will be cut off when the blower is off.

Input from protective port. If the machine needs to be
protected in the special state (such as door open protection),
the protective signal can be inputted from this pin. This pin can
be enabled and prohibited. This signal is not inquired by the
mainboard if this pin is prohibited; if this pin is enabled, when
the input is high-leveled or this input port is suspended, the
machine will be protected, the work suspended and the laser
closed.

FootSW
Input port of foot switch. The connection method is: when the
pedal is stepped down, the low-level signal will be inputted to
this port; when the pedal is released, the port will be
disconnected or the high-level signal can be inputted to this
port; when the stepped-down pedal is held for not less than
100 ms, if the machine lies idle, it can be started for work; if
the machine is in the working state, the work will be
suspended; of the machine is in the suspension, the work will
be restarted, that is to say, the function of the pedal switch is
the same as that of the “Start/Pause” key. If the interval time to
the first stepping-down of the pedal should be less than 1.5
seconds when the pedal is stepped down once again, the
second stepping-down of the pedal will be considered invalid
by the mainboard.

The spacing polarity is optional, that is to say, when the motion axle reaches the
spacing position, it will trigger a low-level signal so as to make the corresponding LED
(under the cover) light; when the motion axle leaves the spacing position, it will trigger a

8
high-level signal or disconnect the spacing signal so as to make the spacing indicator go
out, but when it leaves the spacing, the corresponding indicator will light and the spacing
polarity become positive. The mistaken setting of spacing polarity will result that the
spacing can’t be detected when the system is reset so as to lead to the collision of axles.

The polarity of directional signal for driver pulse signal can be set. Where a certain
axle is reset, it will move to the opposite direction of machine origin, which means the
polarity of directional signal for this axle is not correct. In such a case, the connection
between this axle and the motor driver can be broken first (otherwise the mainboard can
not be detected to the spacing so as to lead to the collision of this axle), and then such a
polarity can be corrected after this axle is reset completely. Upon the correction, the reset
key can be pressed against to reset the mainboard.
4.6 Laser Power Control Interface CN6/CN7

6 Examples of Driver Interface for Step-servo Motor
6.1 Overview
The input signal end of step-servo motor driver employs the light-coupled isolation
technology. For the step-by-step impulse signal, some isolate the side OC diode from
cutoff to conduction (e.g. the valid falling edge of pulse signal inputted from the diode
minus end) and some do so from conduction to cutoff (e.g. the valid rising edge of pulse
signal inputted from the diode minus end). When it is indicated whether the pulse signal of
motor driver is the valid rising edge or the valid falling edge, it will be subject to the pulse
signal inputted from the minus end of side OC diode.
Some input signals of motor driver are independent and some are internally of
common anode, so some have 4 external leading-out wires and some 3 wires (only the
pulse and directional signals are counted) as shown in Figure 10 and 11. Meanwhile, the
input signal can generally be compatible with different voltage classes. If it is higher than
the 5V signal, it is necessary to connect the current-limiting resistance externally. The
interface signals of motor driver for RD mainboard are the 5V signals that should directly
be abutted with the corresponding terminals to the driver.
The interface pulse end of each motor driver for RD mainboard can provide such two
signals as the rising-edge walk and falling-edge travel. The improper use of the pulse-end
signal may give rise to the lost steps, even back-run and finally dislocation of processed
figure when the motor steers. In addition, this mainboard provide two directional signals
not restrict in requirements. Either signal can be connected with the directional signal end
of driver in the common-anode mode. Both directional signal ends can also be connected
with the driver in the differential mode. In such a case, plus and minus can be exchanged
at random. The result of exchange is that the rotating direction of motor is different from
the actually desired direction. At this time the polarity of directional signal for the motor
can be modified on the PC software. In this section is exampled the driver of step-servo
motor popular in the market. In addition to that the correct wiring scheme of this
mainboard and motor driver is provided, it is recommended to use the common-anode
connection in all wiring schemes.

the valid rising edge. Some of its products can support the mode of valid rising/falling
edge. When these products are delivered out of the factory, they are all set at the valid
rising edge; if the user changes the ex-factory setting into the valid pulse falling edge,
Section 6.3 can be referred to for the wiring method. For the typical models such as M860
and 3MD560, Figure 6.2-1 and 6.2-2 show the wiring scheme of RD mainboard and
Leadshine driver.
