Set the distance from the Scan bar to the Center of each Head, Spray and Brush

Sensor enabled

Sensor disabled

N.B. Two adjacent sensors cannot be disabled. Only disable alternate sensors.

Procedure

• and check ENCODER increases (Analog out +1 Volt)
• and check ENCODER decreases (Analog out -1 Volt)
• A - A' = Maximum MEASURE
• Note the start position (A)
• Zero-set ENCODER
• Move the axis from A to A'
• Note the ENCODER reading and enter it in PULSE
• Measure the distance from A to A' = space delta
• Enter the A - A' space delta in MEASURE

Important:

• PULSE must always be greater than MEASURE (recommended MEASURE x 10 = PULSE)
• Enter MEASURE in the set unit measure format. e.g. unit measure = 0.1 mm and space delta = 133.5mm, enter 1335 in MEASURE

Settings in yellow can be modified for the calibration.
Service data is in green and only used for the setup procedure.

First complete the following procedures:

• RESOLUTION: set the resolution.
• MAX POSITION: enter a very large positive setting (e.g. 99999.9 mm)
• MIN POSITION: enter a very large negative setting (e.g. - 99999.9 mm)

IMPORTANT! Essential conditions for the all procedures:
The emergency button must shut off the power to the motors so that the machine is in a safety condition.

All emergency conditions on the machine must be eliminated.

Procedures

Offset
1	to start calibration
2	Set VOLTAGE OUTPUT = 0
3	Regulate the OFFSET (directly by , or automatically ) so that POSITION does not vary (or varies very slowly)
4	to quit calibration

Rotation direction and count
An output voltage > 0 increases POSITION
1	to start calibration
2	Enter VOLTAGE OUTPUT = 1.0
3	Check that POSITION increases
4	to exit calibration and check that VOLTAGE OUTPUT goes to 0 immediately
5	If the motor does not rotate in the correct direction, change the drive setup or cabling

Maximum speed
Setting the maximum axis speed (10V output)
1	to enter calibration
2	Enter VOLTAGE OUTPUT > 1.0 (as close to 10V as possible)
3	Note the SPEED reading
4	Calculate the MAX SPEED: MAX SPEED = (10 x SPEED) / VOLTAGE OUTPUT
5	to exit calibration and check that VOLTAGE OUTPUT goes to 0 immediately
6	Enter the above calculation result in MAX SPEED

The PI + FF calibration procedure:
Space feedback corrects the axis position according to the follow error reading.
Settings in yellow can be modified for the calibration.
Service data is in green and only used for the setup procedure.

First complete the following procedures:

• RESOLUTION: set the resolution.
• MAX POSITION: enter a very large positive setting (e.g. 99999.9 mm)
• MIN POSITION: enter a very large negative setting (e.g. - 99999.9 mm)

IMPORTANT! Essential conditions for the all procedures:
Ensure that the emergency button shuts off the power to the motors so that the machine can be put in a safety condition.

All emergency conditions on the machine must be eliminated.

Procedure

Space Feedback
Important: first complete all previous procedures
1	Enter FEEDFORWARD = 100.0
2	Enter PROP. GAIN = minimum setting (0.001)
3	If FOLLOW ERR is not 0, now this reading will reduce with an axis movement
4	Enter DELTA = any distance and SET SPEED = a speed (nearly MAX SPEED)
5	to start the axis movements
6	The axis moves forward by the distance in DELTA at the speed in SET SPEED
7	The axis then returns to the start position and repeats the movement
8	During the movements note the FOLLOW ERR reading and vary FEEDFORWARD and PROP. GAIN to keep it as low as possible. Setting rules Gradually increase PROP. GAIN until the axis does not vibrate when stopped. Then slightly reduce the setting to until ok Rule for varying FEEDFORWARD FOLLOW ERR. >0 <0 Direction Forward Increase FEEDFORWARD Reduce FEEDFORWARD Backward Reduce FEEDFORWARD Increase FEEDFORWARD
9	When the axis movement overshoots MAX FOLLOW ERROR you will see the warning symbol , it does not create an alarm stop
10	to quit the procedure
