Subject to change without notice
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 protective hose.
•
Connect directly via M12 round screw system or cable connection.
•
The rotatable male connector / cable connection is intended only for aligning
the male connector / cable connection during mounting, not for permanent move‐
ment.
•
The enclosure rating for the connector outlet can only be achieved with the mating
connector screwed into place.
Tightening torque for the mating connector at an M12 male connector outlet: 1.0 Nm
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 REFSIN.
•
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 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.
