Evaluation of Motor Control Software Projects through CCS
–
Kp: Sets the proportional gain for the current controller
–
Ki: Sets the integral gain for the current controller
–
Start-up current: When current control is active the motor is driven with constant current rather than
a constant duty cycle during the forced commutation ramp up phase. This slider sets the current for
this phase
•
Velocity loop: These parameters are associated with the velocity control loop. These parameters are
only active when control mode is set to velocity or cascade. Velocity and cascade are the only modes
which make use of the velocity loop.

Kp: Sets the proportional gain for the velocity controller
–
Ki: Sets the integral gain for the velocity controller

Velocity loop limit
•
In velocity control mode, the velocity loop limit slider sets the maximum PWM duty cycle to the
motor
•
In cascade control mode, the velocity loop limit slider sets the maximum current to the motor

Shutting Down
When finished evaluating, uncheck the enable motor check box to stop the motor. When the motor comes
to a full stop, the GUI can be closed. Now, turn off the DC power supply.
WARNING
Because the capacitors are charged, the VM may remain on for a
couple of seconds, do not touch any parts on the board
immediately after shutdown.

Evaluation of Motor Control Software Projects through CCS
The hardware resource mapping for TMS320F28035 controller inside DRV8303EVM kit is exactly similar
to DRV8301-HC-C2-KIT. All the motor-control software projects supplied through controlSuite for
DRV8301EVM can be directly ported to DRV8303EVM without any modifications.
The following projects are currently available for the DRV8301-HC-C2-kit at
controlSUITE\development_kits\DRV830x-HC-C2-KIT_v104.
•
PM_Sensorless: Sensorless field oriented control of permanent magnet motor
•
BLDC_Int: Sensorless trapezoidal control of BLDC motors based on BEMF integration

Motor Control Experiment HW Setup Instructions
Follow the hardware setup instructions described previously in
. except for the following change
in the SW1 setting. In order to enable JTAG connection, keep the switch SW1: ON (up) position.
5.2
Motor Control Experiment SW Setup Instructions
In order to build and run the prior projects using CCS, please refer to
for DRV8301-HC-C2-
Kit projects.
