5.2 Signals of the encoder system
The SKS36S/SKM36S safe motor feedback system has the following HIPER‐
FACE® interface signals:
•
V
S
– Supply voltage to the encoder. The operating voltage range of the
encoder is b 7 V and +12 V. The recommended supply voltage is +8
V.
•
GND - Encoder ground connection; electrically isolated from the housing. The
voltage relating to GND is + U
S
.
•
+ SIN – Process data channel; + SIN is a sine signal of 1 Vpp with a static
offset of REFSIN.
•
REFSIN – Process data channel; a +2.5 V static voltage which serves as the
reference voltage for +SIN.
•
+ COS – Process data channel; + COS is a cosine signal of 1 Vpp with a sta‐
tic offset of REFCOS.
•
REFCOS – Process data channel; a +2.5 V static voltage which serves as the
reference voltage for + COS.
•
Parameter channel; positive data signal. The parameter channel is an asyn‐
chronous, half-duplex interface, which physically conforms to the EIA RS485
specification. For this, data can be requested from the encoder through dif‐
ferent commands; this also makes it possible to write user-specific data
such as position offset to the EEPROM of the encoder
•
Parameter channel; negative data signal. The parameter channel is an asyn‐
chronous, half-duplex interface, which physically conforms to the EIA RS485
specification. For this, data can be requested from the encoder through dif‐
ferent commands; this also makes it possible to write user-specific data
such as position offset to the EEPROM of the encoder

Commissioning
To commission the safe motor feedback system, SKS36S/SKM36S, it is assumed
that the manufacturer of the connected drive system has complied with the safety
requirements for the drive system design, as described in the implementation
manual, "Hiperface Safety".
Further measures are not required for commissioning.
6.1 Inspection instructions
Further inspection measures are not required for commissioning and during oper‐
ation.
WARNING
Observe the mission time!
The SKS36S/SKM36S safe motor feedback systems have a specified maxi‐
mum mission time, after which they must always 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 year of manufacture of the motor feedback system is specified on the device
label and/or packaging label using a four digit code (yyww). The first two digits yy
specify the year (without the century), the last two digits ww specify the calendar
week of the last manufacturing process.
6.2 Declaration of conformity
The SKS36S/SKM36S safe motor feedback system family was manufactured in
accordance with the following directives:
•
the machinery directive 2006/42/EC
•
the EMC directive 2014/30/EU
The complete EU declaration of conformity is available at the SICK homepage on
the Internet: www.sick.com
