6.15 Rotating to the reference position
Each time the machine is switched on the stepper motor rotates
to the reference position and then returns to the current upper
transport length in order to set the upper transport length. This is
necessary to ensure that the value shown in the display agrees
with the actual upper transport length.
Figure 49: Checking the reference position
Checking rotation to the reference position
1. Tilt the machine upper section backwards.
2. Switch on the machine at the main power switch.
After the internal system test has completed, the stepper
motor rotates to the reference position.
When the reference position has been reached, the
LED (1) on the inductive sensor (2) lights up briefly.
The motor then rotates to the current upper transport
length position.
3. Erect the machine upper section again.
Risk of injury from sharp and moving parts.
Do not reach into the area of moving machine parts
while testing the reference position.
