reference switch function (GND: X30/X40) (refer to the Overview circuit diagram for the
respective reference switch J1042-8...).
• Move the corresponding drive far enough so that the reference position is reached on
the service PC (Diagnostic; Monitoring) (Refer to the chapter on adjusting the drives).
• Adjust the reference switch by moving it in the X direction. The switch should activate
within the mechanical limits of the switching hysteresis ((Fig.5/p.36)).

The switch can be ON or OFF within the range "X".
For the actual value potentiometers and reference switch test points on board D5, refer to
wiring diagram J1042-8x.
c) Checking synchronization of the actual value potentiometers to the motor encoder
NOTE
Adjustment of the MC position with the ADC position
- When the system is switched ON or board D1 is reset with button S1, the value of
"MC position" is adjusted to the value of the "ADC position.“ (initialized).
- If the ADC position deviates from the MC position, the error "428x AD / MC position
comparison failure / x“ is displayed (x corresponds to the number of the drive).
Reason for the error message
- Potentiometer Actual value Rx not synchronous to the motor encoder Bx.
Maximum acceptable differences in the ADC/MC positions
ZL, ZR = 25 in 1/10 mm W = 30 in 1/10 mm X = 30 in 1/10 mm Y = 30 in 1/10 mm
Starting with software VA00D (Software Upgrade Rev. 3), the physical limits of the drive are monitored.
O = 90 in 1/100° TL = 18 in 1/10 mm TR = 175 in 1/100°
Checking the display for the corresponding drive in the service PC
"MC position" and "ADC position" are displayed on the service PC (Diagnostic, Monitoring).
• Move the respective drive into an end position.
• Reset board D1 with button S1.

• Check the respective adjustment for the drive ("MC position" to "ADC position") on the
service PC (Diagnostic, Monitoring).
• Move the drive to the opposite end stop in 5 steps.
• Perform a check at the service PC.
NOTE
Procedure for tensioning the toothed belt:
If the deviations of the ADC/MC positions are greater than the maximum acceptable deviations, the drives must be checked. If there
are errors in the lifting columns and/or the cone drive, they must
be replaced, since the actual value potentiometer cannot be adjusted.
• Loosen the screws at the idler pulley of the corresponding potentiometer toothed belt.
• Tighten the toothed belt by shifting the idler pulley and retighten the retaining plate.
• Reset board D1 with button S1.
• Perform a functional check as described above.
• Loosen the idler pulley again if shifting the idler pulley does not adjust the belt ade-
quately.
• Remove the retaining plate for the toothed belt end stop.
• Open the clamping piece of the toothed belt, shorten the belt by removing 4 teeth (2
teeth each parallel), insert the belt and reassemble completely.
• Perform a functional check as described above (check hysteresis of the reference
switch).
