9.3.1 Replacing the drive unit
If it is necessary to replace a drive unit gearbox, the complete motor unit must be dismantled from the recipro-
cator base. Therefore, the reciprocator has to be free of load and disconnected from mains.
Procedure:
1. Let the Z carriage (7) move down onto the lower stop.
2. Remove all cover plates from the reciprocator.
3. Remove the locking plate (5)
4. Uncouple the cable to the incremental pulse generator (encoder) from connection X8

5. After loosening the belt, loosen the 4 screws (1) at the point where the motor is attached to the robot.
6. Its engine is outside through the openings on both sides of the robot.
7. To remove the timing gear on the engine; loosen the 2 setscrews attached to the gear unit and
remove one completely. Insert the screw you removed into the 3.setskur blank, which is normally
empty, and tighten it securely. The gear will come off and disengage on the engine.
8. To remove the encoder, simply unscrew the 2 screws where it is attached to the motor.

8.4. Drive belt

WARNING:
Injuries can arise if fingers, hair or articles of clothing get caught between the drive belt and
the drive wheel or toothed wheel.
** All work must be carried out only by technical personnel
The drive belt (3) should be checked regularly because it is exposed to large loads when in operation:
Procedure:
- The drive belt (3) should be checked for wear and tension every 6 months. Powder deposits should
be removed with a vacuum cleaner, because this can influence the quiet running and shorten the service life of the
drive belt.
- Switch on the reciprocator and check the Z carriage (7) for quiet running. Check the drive belt (3) for
elongation or wear (noisy running, strong vibration of the belt when reversing the direction of travel).
9.4.1 Replace the drive belt
Procedure:
1.Let the Z carriage (7) move down onto the lower stop.
2. Switch off the electric power.
3. Remove the boarding (side panels).
4. Remove the locking plates (5) and loosen the tensioning screws (2) , so that the drive belt (3) is slack.
5. Loosen the lower locking plate 2 with the drive belt on the Z carriage (8) and set it down. Note the
position of the locking plate on the drive belt holder, because it must be fitted in approximately the same
position on the assembly.
6. Remove the damaged drive belt from under the reciprocator.
7. Loosen the screws on the upper locking plate 1 and remove the drive belt when it is completely outsi-
de of the reciprocator.
8. Screw on the new drive belt at the upper locking plate 1.
9. Pass the loose end of the drive belt over the upper toothed drive wheel from inside the reciprocator
column.
10. Screw on the drive belt at the lower locking plate 2.
11. Tension the drive belt, but do not overstretch.
