opening not only new revenue
sources but also new customization
skills, adaptation capability and
efficiency, high quality, user
friendliness and minimized efforts.
This is just part of the complex,
feature-oriented solution
development within the Industry 4.0
and Smart Home world which
has already started.
Welcome to modern, feature-oriented pro-
ductivity and growth with its own modern
functionality like omnipresent wireless com-
munication and IoT ability. This demand
has to be considered, added and fulfilled as
a requirement automatically within the solu-
tion development phase. It’s a mandatory
step that enables manufacturers to accelerate
the development of new competencies and
increase their ability to become more agile,
efficient and predictive. Growing innovation,
reinforcement of the request-oriented and
customer-centric approach are the require-
ments for rapid return and new revenue
sources. The end development of a complete
solution also requires simplified but effective
maintenance, support and services during
the solution warranty and lifetime. Those
attributes as a differentiator, combined with
the skill of customized and user friendliness,
are very important factors that influence the
successful outcome of the solution and the
satisfaction of the end user and customer
nowadays. Renesas provides reference designs
which are able to fulfil the needs of fast and
cost- optimized solution development. This
includes modern state of the art add-on fea-
tures that enable future oriented function-
alities within the motor control solutions
area. The attributes of the reference designs
delivered include sophistication and com-
plexity moving towards simplicity, targeting
higher efficiency, quality and flexibility with
the implementation of new modern add-on
features. Products include the YROTATE-
IT-RX23T, YROTATE-IT-RX24T and YRO-
TATE-IT-S5D9. All three reference design kits
are available for single/dual motor control
(PMSM, BLDC, AC induction).
The main characteristic related to the control
methodology is as follows: speed and torque
control, sensorless Field Oriented Control
(one- and three-shunt method), usage of
Hall sensors and/or encoder unit ability, auto
tuning, identification and calibration func-
tionality, intuitive PC graphical user interface
(PC-GUI), interface for an external high volt-
age/high current power stage (up to 1.5KW),
proprietary debug Interface E1, and safety
compliance Self-Test library IEC60730, and
certificate by VDE.
Included within the control methodology of
the available reference designs, the follow-
ing modules and functionalities expand the
development options and enable more agil-
ity and smartness: ALSTC (Adaptive Low
Speed with maximum Settable Torque Con-
trol), ASO (Adaptive Speed Observer), ABC
(Adaptive Boost Control (patented method by
Renesas)), Wireless PMOD interface enabling
usage of BLe, BT and Wi-Fi technology, Smart
APP for iOS and Android based devices (YRO-
TATE-IT), Exchange Data by Email, SMS and
Cloud Services is also possible. With one of
the mentioned reference designs in the labo-
ratory, developers can learn fast and familiar-
ize themselves with the appropriate device as a
component and the methodology behind the
entire system. The possibility of a rapid pro-
totype development and the ability to con-
centrate on the specific add-on functions of
their own solution automatically lead to faster
development and time to market.
Moving on to the next step, Renesas pro-
vides additional sources of feature sets and
functionalities with the YROTATE-IT-XXX
reference designs. These enable the imple-
mentation of wireless communication ability
by enabling rapid test and evaluation through
data capturing and sharing. These capabilities
are easy to apply within the evaluation process
and can be expanded with additional func-
tionalities within the framework and end-de-
velopment process.
The capability of wireless communication has
been accomplished by integrating the PMOD
adapter interface. This enables the implemen-
tation of PMOD- based devices by supporting
one of the wireless communication technolo-
gies like BLe, BT or Wi-Fi. The YROTATE-IT-
RX23T and – S5D9 reference kit now supports
the Bluetooth low energy (BLe) wireless com-
