Refitting, motor axis 5
The procedure below details how to refit the motor, axis 5.
7. In order to release the brakes, connect the
24 VDC power supply to the motor.
Connect to connector R3.MP4:
• + : pin 7
• - : pin 8
8. Start with a play in all positions and then
find the smallest play by turning the motor
shaft six turns and thereby finding the area
with the smallest play within this range.
Use swift movements to avoid noticing the
magnetic field, which makes the gears stick
together.
9. Push or tap the motor in radial direction so
that the play becomes minimal within one
motor turn, without the gear “chewing”.
Do
not use force!
10. Tighten the motor attachment screws and
secure them with locking fluid.
Tightening torque: 4.1 Nm.
