X Turn the adjusting screw of the drive belt as far as it will go. Before doing this you will need to loosen
the lock nut.
X Loosen the two clamping screws on the mounting block of the motor.
X Use the adjusting screw 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.
X Firmly tighten the clamping screws and varnish them with red screw locking varnish.
X Check the belt tension again.
X Secure the cover plates and dock the MTC2 onto the SIPLACE station (see the User Manual).
X Check the zero offset of the feed axis -> „Teach the zero point", if you have changed the belt tension.
Checking and setting the toothed belt
X Carry out the relevant preparations (see Section ( Preparations
J
590 ) ).
X Measure the belt tension with the belt frequency measuring device in the following way:
X Make the toothed belt oscillate and measure the frequency - from the underside of the belt - in the
middle, between the outer deflection pulley and the first deflection pulley of the drive (for the
measuring point, see Section ( Tools and Equipment
J
590 ) ). Make sure that the driver is
approximately in its reference position.
X You must set the belt tension if the measured frequency deviates from the nominal value (70 Hz ± 2
Hz):
X Place the open-ended wrench on the setting flats of the eccentric axis.
X Loosen the clamping screw on the eccentric axis and maintain the position of the axis with the open-
ended wrench.
X Raise or lower the belt tension with the open-ended wrench (turning it in a direction depending on
the position of the eccentric axis), until the nominal frequency is achieved. Firmly tighten the
clamping screw each time you measure the belt tension and varnish it with red screw locking varnish.
X Check the belt tension again and make sure the screws are varnished with red screw locking varnish.
X Secure the cover plates and dock the MTC2 onto the SIPLACE station (see the User Manual).
X Check the zero offset of the feed axis -> „Teach the zero point", if you have changed the belt tension.

Tools and accessories
1 set of Allen keys,
1 set of screwdrivers
Preparations
X Check the zero offset -> "Check the zero point".
X Check the transfer position -> "teach transfer position".
Setting the limit switches
X Move the feed axis into the transfer position (see Section ).
X Set the maximum position of the limit switch above its limit switch holder until there is a distance of
approximately 1 mm between the driver in the transfer position and the contact roller of the limit
switch.
X Move the feed axis into the zero position --> „Check the zero point“.
ATTENTION:
Before the limit switches are set, the zero offset and the transfer position must be checked (see
Section (14.3.2.2 Feed axis
J
575 ) ).

X Set the minimum position of the limit switch above its limit switch holder until there is a distance of
approximately 1 mm between the driver in the zero position and the contact roller of the limit switch
(approximately 10 mm on tower 2).
X Check the feed axis end positions --> „Check and calibrate the travel range end positions".
