Ensure that the supply voltage to the motor feedback system’s DSL female con‐
tact (10) is from +7 V to +12 V.

Mounting
This chapter describes the mounting of the safe motor feedback system.
NOTE
Depending on the motor design, it may be necessary to perform the electrical
installation before the mechanical mounting.
NOTE
If the safe motor feedback system has to be removed, the mounting steps are
to be carried out in reverse order.
NOTE
No impacts or shocks are permitted during the mounting of the motor feed‐
back system.
4.1 Safety
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
appropriate 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 fix‐
ing 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 sys‐
tem:
°
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
4.2 Mounting procedure
Block the customer's drive shaft.
b
Carefully push the encoder (2) onto the motor shaft. Ensure that the center‐
ing 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.
b
Turn the encoder (2) until the holes in the fastening straps (5) are positioned
over the motor’s mounting holes.
b
Attach the encoder housing to the motor end plate by alternately tightening
2 M3 screws (6). Tightening torque: min. 0.6 Nm
b
Pre-mount and tighten screw (7) 2077358, 2088239, or 2088240. Tighten‐
ing torque: 2.2 Nm ± 10%.
NOTE
For full load operation, the cure time of 6 h at room temperature must be
adhered to (see

Electrical installation
NOTE
Observe the corresponding operating instructions of the external drive system
or the higher-order control system for the installation of the motor feedback
system.
NOTE
Make sure the affected machines/systems are in a de-energized state during
mounting!
5.1 Shielding connection
NOTE
A suitable encoder shield connection to the ground or to the motor shield is
required for smooth operation.
The encoder is connected to the motor housing via the screws (2).
5.2 Signals of the encoder system
The motor feedback system has the following signals:
HIPERFACE DSL
®
interface:
•
DSL+: Supply voltage for the encoder with superimposed positive data signal
•
DSL–: Encoder ground connection with a modulated negative data signal
Temperature sensor:
•
T+: Positive potential for the passive temperature sensor/temperature resis‐
tor
•
T-: Negative potential for the passive temperature sensor/temperature resis‐
tor
