5.2 Reference Run Gantry

5.2.1 Reference Run Sequence at X and Y-axis

When performing a reference run with bumper

detection, proximity switch queries are no longer

used. Instead, the reference run continues until

the mechanical end stop (bumper) is reached. The

reference pulse is searched for in a set region of

the incremental scale.

The axis travel direction is reversed, if the set

target value is not reached by the axis(target value

≠ actual value). The zero pulse will then be

searched for in a set part of the incremental scale.

After reaching the zero pulse, the axis will stand in

a defined position.

5.2.2 X and Y commutation position search

A commutation position search for the 3 phases AC-drives on the gantry starts right after the head axis

reference run is succesfully finished.

Starts reference run for main axes at all 4 gantries:

1. Reference motor commutation .

2. Referencing the measurement system.

After detecting the end position bumper, the axis searches for the zero pulse in a specific range . If

the axis detects several or no zero pulses, it will stop and an error message will be issued .

3. Approaching the zero point correction value

4. Reference run of main axes completed, height reference run starts

5.2.3 Reference run of X- and Y- axes

Starts reference run for main axes at all 4 gantries:

 1. Commutating the motors

 2. Referencing the measurement system.

After detecting the end position bumper, the axis searches for the zero pulse in a specific range . If

the axis detects several or no zero pulses, it will stop and an error message will be issued .

 3. The axes are now in a defined position.

 4. Reference run of main axes completed, height reference run starts

5.3 Reference Run C&P12

General procedure

 The reference run procedure is identical to that for C&P12 type DLM3.

 The reference run starts with the initialisation of all the head stepper motors. This allows then, the

head axis to reference by moving first to their zero pulses and then to their zero point correction

values.

 In SIPLACE D4 machines, all heads and gantries move into the reference position at the same time.
