Board Transport Belt Speed (Auxiliary Rails)
The board transport belt speeds of the two auxiliary rails are controlled by the
M27 and are not adjustable. The belt speed can be measured using a tachometer
on the input or output pulley, check the speed to be approximately 500mm/sec
(30m/sec).
Board Transport Belt Speed (Print Station Rail)
WARNING
LETHAL VOLTAGE. DANGEROUS VOLTAGES EXIST IN THIS
EQUIPMENT. ENSURE ALL ELECTRONIC COVERS AND MAIN
MACHINE COVERS ARE FITTED BEFORE OPERATING THIS
EQUIPMENT.
The front and rear board transport belts, of the print station rail, are driven
independently by two variable speed motors. Inevitably one motor drives faster
than the other motor. It is necessary to calibrate these motors so that they drive
at the same speed in either direction. Therefore, the faster motor must be
calibrated to match the slower motors speed.
The speed of both the belt motors is controlled by a MultiMove card situated in
the machine control enclosure and utilizes Pulse Width Modulation (PWM).
This is achieved by controlling the period of the ON control pulse provided by
the MultiMove control card. The pulse repetition rate is fixed at 125Hz.
The belt speed is measured using a tachometer on the underside of the input or
output pulley and adjusted by using the Belt Speed Calibration Page in the
machine diagnostics.
NOTE
For belt speed calibration set up see Calibration Procedure of this section. For
detailed information on access and use of the diagnostics module refer to the
Diagnostics chapter of the machine’s User manual.
Motor speed software parameters is listed in the following table:

input or output pulley of the print station front belt motor, measure the speed
of the motor left to right. Adjust the motor speed using Incr./Decr. to achieve
a speed of 59 - 61 metres/min.
4. Repeat Step 3 for the front right to left motor speed.
5. Repeat Steps 3 and 4 for the rear belt motor.
6. Select Save, the speed of the front and rear belts motors in both directions
are now saved in the machine configuration file.
7. Select Exit.
8. Select Exit.
9. Select Exit.
NOTE
If boards do not butt against the camera board stop during the print sequence,
use the Run on Delay parameter available in the Edit Data menu. If the
condition persists, a reduction in the speed of the transport belt motors maybe
appropriate.
