BOARD SETUP
A step-by-step connecting procedure is available in Section 1.4.3 “Connecting the
F1 LV Evaluation Platform to the Add-on Board”. If using the ebm-papst motor,
attach the ribbon cable from the motor at step 2. Also, make sure that POR R4 on the
evaluation platform is turned fully CCW.
If using a different motor, connected through J2, please keep in mind to attach each
motor phase firmly to the connector. The red connector supplied with the board is
designed to accept 22 AWG wire. Bad contacts can damage the add-on and will wear
out the motor in time. There is no rule for attaching a specific motor lead to a phase line
on the add-on. Keep in mind the correspondences on the software side when testing
or measuring directly on that motor phase.
Adjust R21 90 degrees CCW from the mid-point CCW when operating the ebm-papst
motor. R21 should be set to its mid-point for other motors.

HARDWARE

General Architecture
The BLDC add-on uses a typical three half-bridges control configuration suitable for
three-phase BLDC motors, using six MOSFETS commanded through six bipolar
transistors. Sensorless control is done in the software without any other external
components.

WARNING
The BLDC Motor Control Add-on Board is intended to drive three-phase brushless DC
motors. Before connecting the motor, make sure the power rating of the motor is equal
to or less than the power rating of the board, as shown in Appendix B. “Conversion
Factors”. Also, make sure the configuration parameters inside the software or the GUI
are correct for the motor you are using. Failure to comply with this warning could lead
to malfunction of the board and the motor, and could result in physical harm.
Before beginning the start-up procedure, complete a visual check of the board and the
motor for connectivity and mechanical damage. If damage is found, DO NOT power-up
the board. Otherwise, you may further damage the equipment. Contact Microchip’s
local office or distributor immediately.
