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.
With the motor feedback system with spring plate stator coupling (Fig. 1, 2),
this is ensured using the spring plate stator coupling (5).
5.2 Motor feedback system signals
The motor feedback system has the following signals:
HIPERFACE
interface:
®
•
US supply voltage; the supply voltage is between + 7 V and +12 V, the rec‐
ommended 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
parameter channel is an asynchronous, half-duplex interface, which physi‐
cally conforms to the EIA RS485 specification. For this, data can be
requested from the 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 motor feedback system.

Commissioning
Commissioning the safe motor feedback systems requires that the manufacturer
of the connected drive system has complied with the safety requirements for the
drive system design, as described in the "HIPERFACE
manual.
6.1 Checking
Further inspection measures are not required during operation.
WARNING
The safe motor feedback system has a maximum service life (see Chap. 9).
After this time, it must be taken out of service.
The bearing service life must be taken into account in addition to the mission
time. The parameter which is first reached depending on the application
determines the time when the system must be taken out of operation.
The motor feedback system's construction year can be found in the the serial
number (SN) on the device label or on the packaging label (YYWW).
YY = represents the year (without century)
WW = represents the calendar week of the last manufacturing process.

Servicing
The safe motor feedback system is maintenance-free. No repair option is provided
in the event of a defect. Please contact us if you have any complaints.

Decommissioning
8.1 Protecting the environment
The motor feedback system has been designed to minimize its impact on the envi‐
ronment. It consumes only a minimum of energy and natural resources.
Always act in an environmentally responsible manner at work. For this rea‐
b
son, please note the following information regarding disposal.
8.2 Disposal
Always dispose of unusable or irreparable devices in accordance with the applica‐
ble waste disposal regulations specific to your country.
NOTE
We will be glad to help you dispose of these devices. Please contact us.
