Maria,
I just ran some tests with DRV8312 and the included motor. No load.
I used lab10a first (which includes the ability to change the max modulation from the expressions view)
Max Duty = 1.3094 Max RPM = ~6380
Max Duty = 1.15 Max RPM = ~6070…
Steffen,
You can try changing this variable, but I don't think it will make a difference
#define USER_IQ_FULL_SCALE_FREQ_Hz (1459.0) // 4 * Pole Filter Hz
Have you EVER seen this motor run faster than 2.3 kRPM @ 24V? Do you have another controller…
Thomas,
Thanks for the suggestions. You have essentially confirmed my 'plan B' strategy. We've actually ordered the DRV8312 kit to achieve some baseline experiments and confidence. I had indeed intended to move the 3 resistors on the IDK to route the…
Other Parts Discussed in Thread: CONTROLSUITE I am using the Control Suite DRV8312-C2-KIT_v128 InstaSPIN_BLDC project. When I look at the project properties -> C/C++ Build -> Macros there is a System Macro (show parent context macros is checked) CONTROLSUITE_DRV830x_ROOT…
Other Parts Discussed in Thread: MOTORWARE , CCSTUDIO , INSTASPIN-BLDC , CONTROLSUITE , DRV8312 , DRV8301 Hi everybody on TI forum,
This is Siva, am actually working with a 24 Volts 8A BLDC motor in the High current motor control kit with F28069 and…
Floating point is really about ease of use. There are some operations that are slightly faster, but in an overall system you won't see a huge gain.
The DRV8312-C2-KIT ships with the Isolated F28035 controlCARD, but the code is dual built to also support…
Other Parts Discussed in Thread: DRV8301 , DRV8312 Hello,
I want to bay the DRV 8301 ore the 8312 kit to lurn to program and use it for the existing high part (MOSFET'S) of my old controllers now. Though these controllers can switch 72 to 90 V and 500…
Other Parts Discussed in Thread: MOTORWARE , DRV8312 , BOOSTXL-DRV8301 Hi,
I am working with InstaSPIN and tried the labs. Unfortunately I already struggled with the lab 2a. I can process all the steps as described in the MotorWare User's Guide, but…
Ki,
Sorry to bring up this old issue, but I am still seeing a large amount of slow down when using a typical number of items in the watch window when using CCS v6.0.1. I've taken two videos of what I see when I interact with the watch window. I tried…
Hi,
I've been trying to adjust the PWM code of the BLDC_Sensored for the DRV8312-C2-KIT _v128, F2803x. The name of the file is f2803xbldcpwm_BLDC.h. At the moment this code is set to apply PWM to one the upper gates while one of the lower gates is turned…
