Hi Chris,
I ran into a couple more issues.
1) I am having trouble connecting to my board. I am using the drv8301 69M kit. I'm sure the device to connect to is TMS320F28069. Where I am really unsure is the connection. The board came with a USB cord…
Other Parts Discussed in Thread: INSTASPIN-BLDC , LAUNCHXL-F28027F , DRV8312 , BOOSTXL-DRV8301 I just purchased the DRV8312EVM kit (Rev D) and got it working with the pre-flashed image, with the included 24V 4,000 RPM motor, and with a sensorless trapezoidal…
Hello reg2117 ,
I apologize on behalf of TI for the notes in the documentation. I understand the provided example for the InstaSpin BLDC running on the DK-LM4F-DRV8312 kit may not be enough for your specific application. TI's primary focus for motor…

We bought a DRV8353RS Brushless DC Motor Driver evaluation module to facilitate the…
Nope but I am using the DRV8312 kit to run sensored FOC after modifying the available sensorless project. This might be a really stupid suggestion, but have you appropriately altered the number of lines of your encoder in the qep initialization? Is your…

Charles,
The GND_x pins are internally connected to the low-side FETs of each channel. The current that flows through each low-side FET flows out through this pin to the board GND. We recommend a delta of 100mV maximum between these pins and the GND…
No luck I'm afraid Trey,
I tried putting an EALLOW, or as it's done in the motorware program "asm(" EALLOW");", but it makes no difference.
I then tried changing the values of CANME and CANMD using the EcanRegs in the Expressions window to just any…
Hi Chris,
Thanks for the explanation, I tried that and with over-modulation I can achieve higher speed on my motor. Unfortunately what I want is to force trapezoidal waveform output at PWM duty cycle below 100% ( USER_MAX_VS_MAG_PU =1.0) , is this possible…
Other Parts Discussed in Thread: INSTASPIN-BLDC , CONTROLSUITE , MOTORWARE Hi,
I'm testing the InstaSPIN-BLDC solution using DRV8312-Kit (RevD) and 3 phase BLDC motor.
This motor is used in application that require high speed RPM. For example, dental…
