Action
Lift the motor on to the guide pins and let it
hang with the outer end a little lower when
resting on the guide pins. Do not push the
motor pinion into the gear yet.
This is done in order to fit the motor with the
axis-4 motor still fitted.
Remove the lifting accessory and allow the
motor to rest on the guide pins.
Apply the rotation tool and use it to rotate
the pinion when mating it into the gear.
To release the brakes, connect the 24 VDC
power supply.
Connect to connector R2.MP3:
• + = pin 2
• - = pin 5
CAUTION
Whenever parting/mating motor and gearbox,
the gears may be damaged if excessive force
is used.
Use caution and push the motor in position
while at the same time the motor pinion is
slightly rotated.
Pay attention to following points:
• Mate the motor pinion properly to the
gear of the gearbox.
• Do not damage the motor pinion.
Fit two of the attachment screws and wash-
ers.
Remove the guide pins.
Fit the remaining attachment screws and
washers.
Tighten the screws.
Remove the rotation tool.
