Motor feedback systems from SICK
Commutation, position and
speed measurement with the corresponding number of interfaces used to require
three sensors. Today, SICK motor feedback systems offer these functions in a
single device. A consistent mechanical interface allows for a high level of
flexibility. SICK motor feedback systems are also setting standards for
electrical interfaces such as HIPERFACE and HIPERFACE DSL . They meet
important requirements including temperature resistance, high resolution, and
multiturn design. Certification to SIL2 permits implementation of the Machinery
Directive as per EN ISO 13849.
digital evolution: HIPERFACE DSL in motor feedback systems for servo motors
The HIPERFACE “Digital Servo Link” interface is a revolution in
servo drive systems! The purely digital interface is the future. Thanks to the
innovative and interference-free HIPERFACE DSL protocol, all future
communication can be realized using just two wires that are integrated in the
motor cable, and this is always done in a robust and reliable manner.
product families cover the various performance ranges from standard to advanced
in that they all feature the same mechanical interface. Depending on the
performance class, the product families have a resolution of 15 to 23 bit per
revolution over 4,096 revolutions (multiturn). The high level of flexibility in
the connection systems allows for individual solutions. These SICK motor
feedback systems save a service life histogram e.g. of the temperature, service
life and many other parameters, which allows for convenient application
feedback systems for servo motors with HIPERFACE interface
Motor feedback systems with HIPERFACE comprise a combination of incremental
and absolute encoders, successfully uniting the advantages of both encoder
types. Thanks to the use of highly linear sine and cosine signals, the high
resolution required for speed regulation is reached based on interpolation in
the drive controller.
only one mechanical interface, SICK offers solutions for various performance
classes as well. For single turn and multiturn applications.
HIPERFACE interface has become established as the standard interface in the
market as a result of features such as electronic type label, temperature
measurement and many more. It is used by all leading drive manufacturers.
non-contact length measuring systems for linear direct drives
Linear motor feedback systems with HIPERFACE comprise a combination of
incremental and absolute encoders, successfully uniting the advantages of both
encoder types. Thanks to the use of highly linear sine and cosine signals, the
high resolution required for speed regulation is reached based on interpolation
in the drive controller. The sine and cosine signals are generated in a read
head with integrated evaluation electronics which is guided along the
measurement path without touching it.
systems are used whenever measuring systems need to meet the requirements of
high traverse speeds and simple mounting, e.g. on palletizers, paper machines
or linear motors.

robust solution for asynchronous motors
Incremental motor feedback systems are measuring systems that record the
position, the direction of rotation and the speed of electric motors. The
number of lines per revolution determines the resolution. The position is
determined with a reference traverse. The position is then mapped as a result
of the pulses being counted.
motor feedback systems are mainly used for speed control.
They are mechanically and electrically ideally suited for asynchronous
motors. All the common electrical interfaces are available.
vibration-resistant: perfect for installation in synchronous motors
For a reversal of the direction of current, the polarity of synchronous
motors used to be reversed via so-called brushes Current reversal is required
for continual rotary motion.
the introduction of brushless motors, incremental motor feedback systems with
commutation tracks have taken on this task. The mechanical commutation, which
is very much prone to wear, is no longer required. This makes brushless
synchronous motors practically maintenance-free.
