EVSPIN32G02Q1S1 with LIN motor running sensor-less only moving 1 time and 1 turn and stops

[SimpleStep]

Hi,

I am using a EVSPIN32G02Q1S1 with LIN motor (BL23E33-01D-04RO) running in sensor-less only with 6-step moving 1 time with 1 turn and stops. I cannot connect Motor Pilot to the board for some reason (using the boards built in USART output to a RS232/TTL converter).

I have tried this before with a EVPSPIN32F0601S1 and the LIN motor running at 50VDC and reset the motor parameter from 24VDC to 50VDC to match the minimum of the Inverter board both sensor, sensor-less and FOC and 6 Step with the same result but using the Motor Pilot, it kept coming back with Over Current no matter what I changed. 

My supply is 50VDC and runs up to 7 amps, and the current monitor I have connected in line says I am only pulling 0.5 amps when the over current occurs.

So, my question is this.
Does the Motor Work Bench change the parameters of the system settings to match the inverter and motor pair or is that up to me to do?

Any help on this would be great. Thanks in advance.

Hello @SimpleStep, 

Firstly, we apologize for the delay in replying to your post.
If your point is still relevant, for EVSPIN32G02Q1S1, the "overcurrent" signal is a comparison between the CIN and VREF signals and the VCC undervoltage level. Refer to the STSPIN32G0251 Datasheet for more details.

You can check these three signals directly on the board.

For EVSPIN32F0601S1, it is mentioned that the evaluation board is compatible with a wide range of input voltages from 50 V to 280 V. Therefore, 24 V is too low.
