Fig. 5: Push on the coupling hub, motor side
• Push the coupling [1] with the matching drilled hole onto the shaft journal [C].

Fig. 6: Align coupling hub, motor side
1. Maintain distance (Y) è 5.1.3 Coupling alignment.
2. Tighten motor-side clamping screw [2].
5.1.3
Coupling alignment
NOTICE
Axial forces on the shafts of motor and axis.
Axial forces result in failure of the encoder/brake or increased wear.
• Maintain distances.

Fig. 7: Align coupling hub
1. Measure dimension X from the flat surface of the coupling housing [5] to the
cam base of the axis-side coupling hub.
2. Calculate motor side dimension Y = X − Z è Tab. 4 Dimension Z.
3. Adjust motor side coupling hub [1] to dimension Y ± 0.3 mm.

Fig. 9: Mount the motor
1. Push motor and axis together completely. Pay attention to the correct relative
position of the coupling hubs [1].
Ä
There is no gap between motor and coupling housing [5].
2. Fasten the motor to the coupling housing [10] using the screws [5].
5.2
Supporting frame for the axis-motor combination
Fig. 10: Supporting frame for the axis-motor combination
• Support the combination so it is free from tension to avoid damage.
6 In operation
CAUTION
Risk of injury from touching hot surfaces.
The motor connecting kit becomes hot due to the heat dissipation of the motor.
• Do not touch the motor connecting kit during operation or immediately after-
ward.
