1 About this document
Please read these operating instructions carefully before using the SES/SEM70,
SES/SEM90 motor feedback systems or mounting them, putting them into opera‐
tion, or servicing them.
1.1 Purpose of this document
These operating instructions are for giving technical personnel of the machine
manufacturer or operator instructions on the assembly, electrical installation,
commissioning, operation and maintenance of SES/SEM70 and SES/SEM90
motor feedback systems.
1.2 Symbols used
WARNING
A warning indicates a specific or potential hazard. This is intended to protect
you against accidents. Read the safety notes carefully and follow them.
1.3 Associated documents
"HIPERFACE " interface manual, part number 8010701, as of 02.2016 (or
®
newer)
1.4 Maintenance and repairs
The SES/SEM70 and SES/SEM90 motor feedback systems are maintenance-free.
No repair option is provided in the event of a defect. Please contact us if you have
any complaints. The motor feedback system is not intended for repeated mount‐
ing/dismantling.
1.5 Disposal
Always dispose of unusable or irreparable devices in accordance with the
b
applicable waste disposal regulations specific to your country.
NOTE
We will be glad to help you dispose of these devices. Please contact us.
2 Product description
Encoders of type SES/SEM70 and SES/SEM90 are motor feedback systems that
are ideal for the dynamic and precise operation of servo-control circuits due to
their equipment.
The overall system, consisting of encoder, evaluation system, servo inverter, and
motor, forms a control circuit. Actual values for commutation, rotational speed,
direction of rotation, and position are derived from the encoder signals.
The sensor signals are transferred to the evaluation system via a HIPERFACE
interface.
WARNING
The SES/SEM70 and SES/SEM90 motor feedback systems are not safety
components.
3 Generally applicable notes
Switch off the voltage of all affected machines/units during the mounting
process.
The more precise the centering for the motor feedback system, the less the angle
and shaft offset during mounting.
EMC considerations make it mandatory to connect the housing or the encoder to
ground.
The integrated shielded cable ensure this with the SES/SEM70 and SES/SEM90
with shielded cable (part number 2089521).
This must be ensured via the total system with the SES/SEM70 and SES/SEM90
with unshielded cable (part number 2031086).
WARNING
To ensure trouble-free operation, ensure that the motor shielding is con‐
nected properly.
If tolerances are narrow between the motor shaft and the motor feedback system,
pushing the rotor may be more difficult.
When dismantling the motor feedback system, the motor feedback system must
be held on the housing and then pulled off of the motor shaft.
3.1 Preparation for mounting
Degrease the drive shaft if necessary.
b
Look for any damage!

4 SES/SEM70 motor feedback system
4.1 Tools/parts required
3 M3 cylinder head screws according to ISO 4762 (DIN 912) or similar screws
with a minimum strength of 8.8 are required for mounting the motor feedback
system. Select the screw length (at least 20 mm) and screw head type according
to the mounting conditions.
An SW2 Allen wrench is required for mounting or dismantling the hollow-shaft
clamp.

4.2 Mounting
e n
Block the customer's drive shaft.
b
Push the rotor of the SES/SEM70 carefully onto the motor shaft using 4
b
pressure points to ensure parallel alignment of the rotor and the motor
shaft.
NOTE
Please make sure that the centering collar of the motor feedback sys‐
tem does not snap completely into the centering collar of the motor
flange.
A defined gap is created due to the geometry of the centering collar with the
b
forms on the rear side of the motor feedback system. This makes it possible
to adjust the motor feedback system without a mounting tool.
Gently press the rotor down to the stop and tighten the screws of the hollow-
b
shaft clamp in number order (screws 1-5).
Screw tightening torque (hollow-shaft clamp): 0.4 Nm.
In the second work stop, the screws must be tightened in the reverse order
b
from before.
Screw tightening torque (hollow-shaft clamp): 0.7 Nm.
Turn the housing until it engages in the centering collar
b
The housing must be fixed to the flange with 3 screws (not included with
b
delivery).
Screw tightening torque (housing): 1.0 Nm ± 10% Nm.
4.3 Dismantling
Block the customer's drive shaft.
b
Loosen 2 screws of the cable outlet and remove the cover.
b
De-energize and pull out the set of stranded wires and remove the strain
b
relief.
Unscrew the screws on the encoder housing and the hollow-shaft clamp and
b
remove them.
The encoder can be removed. Hold the encoder on the housing and pull off
b
of the shaft.

6 Electrical installation
WARNING
Observe the following points in relation to electrical installation of the SES/
SEM70 and SES/SEM90 motor feedback systems.
To connect the sensors, refer to the corresponding operating instructions for
b
the external drive system or for the higher-order control system.
Never establish or remove electrical connections to the motor feedback sys‐
b
tem with the voltage switched on, since that could result in a faulty device.
