Supports encoders to SIL3 level May 1st 2011 SICK (UK) has introduced Hiperface
DSL, a fully digital encoder feedback
interface with both SIL2 and SIL3
safety capability for the
communication of feedback data
from brushless servo motors to
associated drive electronics.
The Hiperface DSL data protocol
has been designed to carry
comprehensive sensor data from
motor to drive while reducing system
costs. It is suitable for use in a range
of robotic and automated machinery
applications as well as process and
packaging equipment.
Darren Pratt, encoder specialist,
says: "Hiperface DSL is currently the
only motor feedback interface with
the capability of supporting encoders
to SIL3 levels for both safe speed and
safe position functions. In addition,
the protocol requires less expensive
hardware than current digital
encoder feedback systems, enabling
significant cost savings."
The interface is so robust that
cores inside the motor power cable
can be used for the communication
of feedback data to the drive. The
twisted pair traditionally used for the
temperature winding sensor in a
standard motor power cable can be
used for the Hiperface DSL
communication. More articles from SICK (UK) Ltd: |
