WARNING
As soon as the covering tape has been applied, the tape print is no longer vis‐
ible. We recommend marking the covering tape correspondingly.
NOTE
The arrow direction of the sensor print must match the arrow direction of the
tape print.
The location of the sensor compared to the magnetic tape is exactly defined. Dur‐
ing mounting, make sure that there is an air gap between the tape and sensor
over the entire measuring distance, regardless of whether the tape or the sensor
is moved. The supplied distance gage can be used as a mounting aid.
The read head TTK50S can only be mounted with the mounting kit (2109583).
The mounting kit consists of a mounting plate and two countersunk screws.
The read head TTK70S can only be mounted with the mounting kit (2105618).
The mounting kit consists of two titan screws, safety discs, female connectors
and washers each.

1. Mount the countersunk screws (2) and mounting plate (1) as shown.
2. Check the distance between the sensor and tape using the distance gage.
3. Secure countersunk screws (2) with screw adhesive.
4. Tighten countersunk screws. Tightening torque: 1,41 ± 0,1 Nm.

Electrical installation

NOTE
Observe the corresponding operating instructions of the external drive system
or the higher-order control system for the installation of the safe motor feed‐
back system.
NOTE
Make sure the affected machines/systems are in a de-energized state during
mounting!

5.1 Shielding connection

NOTE
Select the area of application so that inductive or capacitative faults cannot
affect the sensor or its connecting cable.
NOTE
A suitable encoder shield connection to the ground or to the motor shield is
required for smooth operation.
NOTE
Install the cable with strain relief. If necessary, provide a drag chain or protec‐
tive hose.

5.2 Safe motor feedback system signals

The safe motor feedback system has the following signals:
HIPERFACE interface:
®
• US supply voltage; the supply voltage is between +7 V and +12 V, the recom‐
mended supply voltage is +8 V.
• GND - ground connection; electrically isolated from the housing. The voltage
drawn is US.
• + SIN process data channel; sine signal of 1 Vpp with a static offset of REF‐
SIN.
• REFSIN process data channel; static voltage of +2.5 V, reference voltage for
+SIN.
• + COS process data channel; cosine signal of 1 Vpp with a static offset of
REFCOS.
• REFCIS process data channel; static voltage of +2.5 V, reference voltage for
+COS.
• Data ± – RS485 parameter channel: negative/positive data signal; the para‐
meter channel is an asynchronous, half-duplex interface which physically
conforms to the EIA RS485 specification. For this, data can be requested
from the safe motor feedback system through different commands; this also
makes it possible to write user-specific data such as position offset to the
E2PROM of the safe motor feedback system.
