CALIBRATIONS

Board Transport

Belt Speed

The front and rear board transport belts (feeder belts) 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. Non-compliance of this calibration could cause boards

to jam in the machine or uneven wear in the rails or transport belts.

WARNING

LETHAL VOLTAGE. DANGEROUS VOLTAGES EXIST IN THIS

EQUIPMENT. ENSURE ALL ELECTRONIC COVERS AND MAIN

MACHINE COVERS ARE FITTED BEFORE OPERATING THIS

EQUIPMENT.

The speed of both feeder 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.

Feeder motor speed is measured using a tachometer on the input or output pulley

and adjusted by using the Belt Speed Calibration Page in the machine diagnos-

tics.

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 User manual.

Motor speed software parameters is listed in the following table:

3. Using a tachometer fitted with the surface speed test wheel, positioned on the

input or output pulley of the front belt motor, measure the speed of the motor

left to right. Adjust the motor speed using Incr./Decr. to achieve a speed of

29 - 31 metres/min.

4. Using Next repeat Step 3 for front right to left motor speed.

5. Select Next use a tachometer fitted with the surface speed test wheel,

positioned on the input or output pulley of the rear belt motor, measure the

speed of the motor left to right. Adjust the motor speed using Incr./Decr. to

achieve a speed of 29 - 31 metres/min.

6. Using Next repeat Step 5 for rear right to left motor speed

7. Select Save, the speed of the front and rear belt motors are now saved in the

machine configuration file.

8. Select Exit.
