5.3.1 Travel range and velocity monitoring X- and Y- Axes on the HF

The travel range of the X- and Y-axes will be determined automatically with Sitest program. That

means, during calibration of travel range the axis run as far as possible into its minimum and/or

maximum position. The axis position is taken when the limit-BERO´s switch. Corresponding the

description (see below) a safety space infront of the hardware limit switch is calculated for SW-

travel limit.

a The end of the travel range of the X-axis be + or - 0,5 mm before the hardware limit switch

(software limit switch).

For velocity check, a range of

45 mm before the hardware limit switch was determined. This

way is sufficient, if the X- axis move with to high velocity into this field. It will be stop by the anti

crash board immediately.

s The end of the travel range of the Y-axis be + or - 1,5 mm before the hardware limit switch

(software limit switch).

For velocity check, a range of

65 mm before the hardware limit switch was determined. This

way is sufficient, if the Y- axis move with to high velocity into this field. It will be stop by the anti

crash board immediately.

5.3.2 Travel range and velocity monitoring X- and Y- Axes on the HF 3

The travel range of the X- and Y-axes will be determined automatically with Sitest program. That

means, during calibration of travel range the gantry 3 went as far as possible into its minimum and

maximum position. Corresponding the description (see travel range HF) a safety space in front of

the hardware limit switch is calculated. At HF 3 machine we have two gantries in the placement

area 1 so the Y-axis of the gantry 1 went to the minimum position and the Y-axis of gantry 4 went

to the maximum position. After that we calculate the minimum position for gantry 4 according min.

pos. of gantry 1. The maximum position for gantry 1 we calculate on the result of maximum pos.

of gantry 4.(see below)

(1) The calculation of the travel range for the X-axes on gantries 1 / 3 / 4 and Y-axes from the

gantry 3 is the same as the HF machine.

(2) The travel range for the y-axes on the gantries 1 and 4 are calculated partly. That means, the

Y-axis of Gantry 1 moves into the minimum position and the Y-axis of gantry 4 moves into the

maximum position. The calculation is:

Maximum position gantry 1 = Maximum position gantry 4 - 480mm (gantry width) - 20mm

safety space.

Minimum position gantry 4 = Minimum position gantry 1 + 480mm (gantry width) + 20mm

safety space.

(3) Safety space approx. 20mm

Please Note: For adjust the Anti Crash board see 5.3.4.

5.3.2.1 Adjustments BERO‘s

On each axis are two BERO‘s installed, which need a distance about 0,4 mm to the metal actuator.

The metal actuator are installed on the left and right side from the incremental scale. Adjust cor-

rectly the distance with a

feeler gauge of 0,4 mm. After this adjustment calibrate the travel range

for the respective axis with the Sitest program.

5.3.2.2 Description of the BERO‘s on the Y-Axis
