Installation
➢ Loosely fix the motor support and drive motor into the installation position, with the 2
fastening screws (2).
➢ Reconnect the electrical connections with the motor. When fitting, note that there is an anti-
twist lock (notch) present. Tighten the connection appropriately.
➢ Run the drive toothed belt around the motor pinion and the spindle toothed wheel and
tension (pretension) the toothed belt at the slot provided, with the help of the motor support.
➢ Set the final belt tension. To do this, tension the drive toothed belt at the tensioning device,
with the help of the tensioning screw (5). This moves the motor support accordingly in the
slots.
⇨
Setting value: Set the belt tension to 235Hz +/- 10Hz.
➢ Tighten the 2 fastening screws (2) on the motor support, check the belt tension and adjust
where necessary.
➢ Seal the 2 fastening screws (2) with locking varnish.
➢ Calibrate the lifting axis..
