TMS320F2800157: HALL Sensor not wroking with DRV8353 with Launchpad F2800157

Part Number: TMS320F2800157
Other Parts Discussed in Thread: DRV8353

Hi,

Initially, we tried with Lauchpad157 & Drv8353 board interface working fine for sensorless without issue.

The same software(Lauchpad157 & Drv8353 board) when adapted to HALL Sensor(Sensored).

The motor is jerking and stops getting the " module over the current fault".

How to resolve the issue?

We have taken base as F280025C as base and adopted for F2800157 .Finally verfied Sensorless on F2800157 Launchpad.

Any help is much appreciated. Thanks in Advance.

    Are you evaluating the universal motor lab project? Did you develop your own program for HALL sensor feedback?

    Did you try the abovementioned HALL sensor feedback-based motor control with F280025C? Did you encounter the same issue?

    Thanks,

    Hi @Jiaxin Teng,

    Thanks for your response.

    We can run the motor with a HALL sensor. The issue is wrongly connected in EQEP1  and the S5 switch position is wrong.

    Connected motor HALL to EQEP2 and S5 position selected to J13.
