14.3.3.1 Belt tension
Tools and Equipment
Belt frequency measurement device (inductive)
2 belt tension strips
1 set of Allen keys
1 set of open-ended wrenches
Preparations
X Empty the MTC2 completely (see the User Manual).
X Move the lifting axis into its bottom position.
X Remove the left cover in front of the electronics board and the covers on the right and the left in front
of the Masterdrives.
X Switch the motor protection switch off (see ).
X To relieve the tension the toothed belts, loosen the brake on the servo motor in the following way to
rest the lifting axis on the buffer:
Check whether the MTC2 has been switched off and is isolated from the power supply.
Disconnect the terminal connector for the external signals from the lifting axis master drive.
Move the cable from Pin 3 to Pin 1.
Attach the connector.
Connect the MTC2 to the power supply and switch it on.
The lifting axis audibly moves a distance of a few mm up to the buffer.
X Check that the lifting axis is actually at its end position.
X Reconnect the cable as it was originally in the following way:
Switch off the MTC2 and isolate it from the power supply.
Disconnect the terminal connector for the external signals from the lifting axis master drive.
Move the cable from Pin 1 to Pin 3.
ATTENTION:
The construction of the lifting axis was change since 05.2005. This means, new spindle, spindle
with counter bearing, motor lifting axis, gear on the motor and therefore new parametersets for
Masterdrives. The MTC2 has the version number 02. The belt tension for the lifting axis was
change, please note!

Attach the connector.
X Switch the motor protection switch on.
X Attach the covers.
X Undock the MTC2 from the SIPLACE station (see User Manual).
X Crank up the MTC2 in a clockwise direction until it stops.

Checking and setting the belt tension
X Carry out the relevant preparations (see Section ( Preparations
J
584 ) ).
X Measure the belt tension with the belt frequency measuring device in the following way:
Find the holes for the measurement head of the belt frequency measuring device on the lifting axis.
Two holes are provided for each of the dual toothed belts (see Section (14.3.3 Adjustments Lifting
Axes
J
583 ) ).
Attach the toothed belt tension stickers (Siemens item no. 00370691-0) onto the belts in this area.
Cause the belts to oscillate and measure their frequency.
You must set the belt tension if the measured frequency deviates from the nominal value [(200Hz ±
5Hz),(210Hz ± 5Hz) see note above]:
Turn the adjusting screws as far as they will go. Before doing this you will need to loosen the lock
nuts.
Loosen the four lock screws on the mounting plate of the motor.
Use the two adjusting screws to raise the belt tension (by turning in a clockwise direction) or lower it
(by turning in an anticlockwise direction), until the nominal frequency is achieved. Tighten the lock
nuts each time you measure the belt tension.
Firmly tighten the clamping screws and varnish them with red screw locking varnish.
Check the belt tension again.
Remove the belt tension stickers.
X Dock the MTC2 onto the SIPLACE station (see the User Manual).
X Check the zero offset of the lifting axis (see Section (14.3.2.1 Lifting axis
J
574 ) ), if you have
changed the belt tension.
