Powering the Board
The board is separated into two power domains*, the low voltage Controller Power domain that
powers the controller and the logic circuit present on the board, and the medium voltage power
delivery line that is used to carry the medium voltage and current like the DC power for the
Inverter also referred to as DC Bus.
1)
Controller Power
comprises of the 5V and 3.3V that the board uses to power the controller
and the logic and sensing circuit present on the board. This power is regulated from the DC bus
by the DRV830x integrated buck converter.
2)
DC Bus Power
is the medium voltage line – up to 60V - that provides the voltage to the
inverter stage to generate 3 phases to control the motor
Note: Do not apply power to board before you have verified these settings!
The kit ships with the control card inserted and the jumper and switch settings pre done
for connecting with the GUI. However the user must ensure that these settings are valid
on the board.
1. Make sure nothing is connected to the board, and no power is being supplied to
the board.
2. Insert the controlCARD into the connector if not already populated.
Special Notes Regarding controlCARD Use
•
Make sure switches are set properly on the controlCARD according to the
appropriate qsg_hw_cncd280xxx.pdf
•
Special notes for using controlCARDs with this motor drive board
o
When using TMDSCNCD28027F
Connect pin 2 of J12 (GPIO-29) to pin 6 of J5 (EN_GATE).
Note, for all MotorWare versions up to _11 this was pin1 of
J11. Changed in _12 due to pin conflict.
3. Make sure the following jumpers & connector settings are valid i.e.
a. JP2 is installed
4. Connect your PC to the kit
a. controlCARDs with on-card XDS100 USB-JTAG:
i. connect USB cable from computer to USB connector on control
card
b. controlCARDs without on-card USB-JTAG
i. connect USB cable from computer to external emulator, and
emulator to 14-pin JTAG header (J21)
5. Connect the motor you want to spin to the “MOTOR” terminal block as shown
below. The order is not important unless a rotor sensor is used. If ground is
available with your motor it should also be used.
