NOTE
Note the following safety notes for the side fixing screws (6) used during mounting:
•
Minimum strength class of 8.8
•
The screw-in depth must be at least 5 thread turns; select screw lengths appropri‐
ate for the installation conditions.
The tightening torque applies if there is already a thread in the motor end plate. If
•
there is no thread, the additional rolling torque depending on the material of the
motor end plate and the drill diameter for the fixing screw (6) must also be taken
into account.
•
Secure screw connections (6) from loosening using screw adhesive.
Spring washers and toothed washers are not sufficient for securing screws!
•
NOTE
Note the following safety notes for the accessory screw (7) (e.g., 2077358, 2088239
or 2088240) used during mounting:
No additional screw locking device is required for the screw (7)!
•
The screw (7) must not be used after the use-by date due to its coating.
•
•
Only use the screw (7) one time. After removing the motor feedback system:
Clean the residue off of the affected threads on the drive shaft.
°
Use a new (unused) screw on the thread during the remounting process.
°
Spring washers and toothed washers are not sufficient for securing screws!
•
The material used for the motor shaft must have a minimum tensile strength
•
of 530 MPa (e.g. structural steel, alloyed steel for quenching and tempering or
alloyed case-hardening steels)
•
The female thread of the motor shaft must be free of dirt, grease, and burrs. A
thread tolerance of 6H must be ensured. For the geometry of the thread, see the
mounting suggestion (taper of the thread infeed in line with mounting suggestion).
The screw should be mounted in one movement without axial feed.
•
Cure time: 6 hours at Rt. Final strength after 24 hours
•
Block the customer's drive shaft.
Carefully push the encoder (2) onto the motor shaft. Ensure that the centering
►
collar (3) of the encoder is cleanly positioned in the centering part for the motor
and the conical shaft (4) is straight when inserted into the cone of the motor
shaft.
Turn the encoder (2) until the holes in the fastening straps (5) are positioned over
►
the motor's mounting holes.
Attach the encoder housing to the motor end plate by alternately tightening 2 M3
►
screws (6). Tightening torque: min. 0.6 Nm
Pre-mount and tighten screw (7) 2077358, 2088239, or 2088240. Tightening
►
torque: 2.2 Nm ± 10%.
NOTE
For full load operation, the cure time of 6 h at room temperature must be adhered to
(see „Note 4.1", page
26).
