FOC Open Loop reverse

Hello,

I'm currently using Open loop mode for debugging my hardware, current readings and such.

I have found by trial and error the best values for the offset and slope of the V/f curve, such that the motors work on the full range of speeds.

However, when I set negative velocities through MCI_ExecSpeedRamp(MCI, Vel, time), the motors do not behave the same as in the positive direction.

If I replace my offset and slope values by the default ones, the motors behave similarly in both directions.

Am I missing some step to make Open loop work with my V/f curve?

On another topic:
How can I obtain the confidential distribution of FOC SDK?
I've phoned ST's sales, which directed me to my local distributors.
I've contacted several distributors on my country. A couple were unhelpful, others had no idea what I was looking for. A couple others said they would redirect my request to ST.
So far I was not able to find anyone who could help me.

How can I contact in ST to help me obtain the SDK?

Best regards
