Mounting the motor

WARNING
Personal injury and material damage
Some motors, especially the 1FL609❑ are heavy. The excessive weight of the motor should be considered and any
necessary assistance required for mounting should be sought.
Otherwise, the motor can fall down during mounting. This can result in serious personal injury or material damage.
NOTICE
Magnetic interference to the absolute encoder due to the magnetic field
To avoid magnetic interference to the absolute encoder, keep the servo motor with an absolute encoder at least 15 mm
away from the devices that produce a magnetic field stronger than 10 mT.
Note
Using the eyebolts
The 1FL609❑ motor (90 mm shaft height) has two M8 screw holes for screwing in two eyebolts. Lift the 1FL609❑ motor only
at the eyebolts.
Eyebolts that have been screwed in must be either tightened or removed after mounting.
To ensure better heat dissipation, install a flange between the machine and the motor. You can install the motor onto the
flange with four screws as shown in the following figure:
