Hall Sensor in Steval IPM 30B

[hu88]

I am trying to control BLDC motor with Steval IPM30 B and Nucleo L476RG as controller. In sensor less mode it is working fine but when I am using Hall Sensor it is not rotating at all and its showing speed feedback error at the starting only. How to solve it.

Also what will be the switch configuration in Hall Sensor circuit in IPM30B.Which switches should be ON .

Looking forward to your response.

Hello @hu88,

 

Verify that UVW and H1/2/3 are correctly connected.
Once HALL sensor connected, check with a scope that H1/2/3 are toggling as expected.
To ease HALL sensor usage, you can use HALL sensor profiler as described in documentation available through "Workbench tool">About>Documentations>Documentation>"User manual" tab>"Motor Profiler Application Note" link, chapter 5.

Switch configuration depends on the HALL sensor output technology. 
SW9 for pull-up (2-3 +3.3V)
SW13-14-15 for pull-down (open for no pull down)
SW16 for Hall sensor supply
SW10-11-12 (closed for no extra RC filtering)

Thanks for the reply.

Switch configuration is now clear and we are able to get hall sensor pulses. We have probed it in oscilloscope by rotating the motor manually and observed the pulses.

But when I am trying to run motor it just don't rotate only. As soon as  i hit run motor speed feedback error comes within a second.

I have used profiler to get the hall sensor parameters. I have put the same parameters.

Please tell how to trouble shoot this error. Does changing these hall sensor parameters will have any effect ?

Hello @hu88,

Did you try using Motor HALL sensor profiler?
