Reference Design Graphical User Interface (GUI)
INTRODUCTION
The Reference Design Kit Graphical User Interface (R DK-GUI) provides an easy way to configu re motor
control system parameters. These parameters are related to the user’s motor type and model. The parameters which can be configured include the following:
■ type of the motor driven;
– 3PH PMDC/AC or BLDC/AC ( trapezoidal driv en) , or
– 3PH AC induction motor, or
– 3PH PMAC or BLAC (sinusoidal driven)
■ number of the poles pairs of the motor; and
■ control method.
Other, more specific parameters include types of control (i.e., Ramp Up Acceleration Speed for the “3PH
BLDC/AC trapezoidal” or Variable Frequency Control for the “3PH AC Induction” motor).
These settings reside in the .h header file used with the design kit software library (see Compiling the Stan-
dalone RDK Libraries, page 16). The .h file is automatically generated by the GUI and/or can be modified
manually by the user. To generate the firmware for the ST7MC microcontroller, the .h file and the software
library must be compiled using the
ec STDV7 v3.10 environments. Th e firmware is then downloaded into th e microcontroller memory (see
GENERATING THE BINARY CODE FILE (.S19) USING STVD7, page 14).
Some features of the GUI are disabled and c annot be used with t he RDK at this tim e, but they are left to
illustrate the complete features of the microcontroller. If you want to use these features, please refer to the
ST7MC Starter Kit at http://www.mcu.st.com.

switched mode
g. g. Synchronous Speed
– the Minimum target rotor frequency in closed loop, express in Hz of mechanical speed

h. Run Settings
When the “From RV1” checkbox is selected, the, Duty Cycle value (or the target rotor speed in the
case of closed loop regulation) is defined by the RV1 potentiometer.
If this box is unchecked, the following options are set by the user:
– the Target Mechanical (rotor) Speed in RPMs (or Hz) if speed regulation is set to “Closed Loop”
(alternate between RPM and Hz settings by clicking on the “RPM” button)
– the Duty Cycle percentage when the motor is run in “Open Loop” mode
Run Settings and Delay Coefficient
When the “From RV2 - RV3” checkbox is selected the value of Rising Delay is defined by the RV2
potentiometer and the value of Falling Delay is defined by the RV3 potentiometer.
If this box is unchecked, the following options are set by the user:
– the B-EMF Rising Edge delay coefficient value (from 0 to 255)
– the B-EMF Falling Edge delay coefficient value (from 0 to 255)
Run Settings and Closed Loop Parameter
– the value of the Integral Coefficient (Ki) of the Proportional Integrative (PI) regulator
– the value of the Proportional Coefficient (Kp) of the PI regulator
– the regulation Sampling Time (in milliseconds)
