RDZ01 LFS Manual
Chapter 5 LFS controller working process
1 Installation
Firstly install capacitive sensor and amplifier correctly. Amplifier should be installed in one side of the head,
and ensure connection between BNC head and capacitance sensors are reliable. And the metal shell should be
conducted with laser head.
Connect the sensor amplifier output signal to the interface of LFS controller. The cable between sensor
amplifier to LFS controller should be not too long, standard length for cable RuiDa technology provided is 8
meters, if the user's machine do not need so long, to ensure the control precision they can remove part of it
properly. Sensor amplifier installed near the head is recommended, and to ensure that shielded cable connected
between sensor and the amplifier is not affected by stress.
Connecting sensor and RDC633XM correctly according to the wiring instructions after the connection
between height sensor and controller,
2 System test
The power indicator on the sensor amplifier will light after system power on, alarm indicator not light, touch
the nozzle with a metal plate, crash indicator on the amplifier will light. So the amplifier works normally.
Notice:
Before system test, amplifier should be calibrated. Please follow the steps.
First, move the laser head to about 1.1 mm distance from the metal surface. Switch to manual mode and
press Z- to moves down the laser head until the distance between nozzle and the surface is about 1mm. Then
measure the voltage between CON3-pin32 and CON3-pin1 on the EPLC. If the measured voltage is not 6.5V, you
can adjust the potentiometer to set the voltage to be 6.5. So the calibration is finished. After that, switch to
automatic mode, press the auto-searching focus button to carry out a auto-searching process. When auto-searching
is finished. The whole calibration is finished and the focus point is set.
Before system test, Set Z axis parameter through "manufacturer parameter" of RDC633X M operation panel:
Direction polarity： Positive
Key motion direction： Positive
Step length: calculated according to pitch of screw and motor PPR
When configuration has been finished, under manual mode, pressing Z+, the motor will rise up. Pressing Z-,
the laser head will move down (Important: please make sure of this!!)
If it moves to opposite direction, you can exchange each other for A+ and A- motor wiring directly, can change the
rotating polarity of motor.
Focus position is set to 1mm in default. Jump height is 10mm, crash alarm rising up height is 20mm, work
finish rising up height is 40 mm.
Design example:
Motor PPR: 4000
Pitch of screw: 4mm
