11.1 Exchanging the drive assembly
Description The “drive assembly” (>>> 3.1.3 "Description of the drive assembly" page 13)
consists of a servomotor, gear unit, intermediate plate and various attach-
ments.
11.1.1 Removing the drive assembly
Preconditions Remove the tool and any additional items of equipment if these impede re-
pair work.
The carriage is secured against unintended motion.
Procedure 1. Release and unplug connectors XM7 and XP7 (>>> Fig. 11-1) from the
sockets.
2. Remove Allen screw (5) and lock washer and take off eccentric.
3. Remove three Allen screws (3) together with lock washers.
4. Attach lifting tackle to the drive assembly and lift it out of the carriage.
5. Remove four Allen screws (4) and lock washers, and separate the gear
unit from the intermediate plate.
6. If the drive assembly is not to be reinstalled, it must be protected against
corrosion before being put into storage.
Warning!
Unintentional motion of the robot and the linear unit can result in danger to
persons and materials. If the robot and the linear unit have reached their dis-
assembly position, shut down the system and take measures to prevent it
from being switched on again unintentionally. If several robots or linear units
are in a system, these must also be switched off and secured against being
switched on again unintentionally.
Caution!
When exchanging the drive assembly, attention must be paid to the specifi-
cations on the rating plate of the gear unit. The designation and transmission
ratio of the old and new gear units must be the same.
Warning!
If work is carried out immediately after the linear unit has stopped operating,
there is liable to be an elevated surface temperature at the motors. The ap-
propriate safety measures must be taken.
Warning!
The drive assembly weighs approx. 100 kg. When removing or installing the
drive assembly, care must be taken to avoid injury by crushing. Protective
gloves must be worn.
Caution!
When moving out the drive assembly, take care not to damage the toothing
of the pinion and racks.
