Dear all,
[PN]: EVSPIN32G4 & Portescap 16ECP52 Ultra EC Slotless Brushless DC Motor (Datasheet as pdf attached)
[VERSION]:
MC Workbench : 6.3.2
WB_to_Mx : 6.2.3.template-24-04-17
STM32CubeMX : 6.14.1
MC Firmware Library: 6.3.2-Full
Target Toolchain : ST STM32CubeIDE
Target Driver : LL - Low Level
Target STM32 FW : 1.6.0
[TOOL]: MC Profiler
[DETAILS]:Motor stutters and profiler stops with error 'Speed Feedback'
[EXPECTED BEHAVIOR]:smooth operation within 100-5000 RPM
[HOW TO REPRODUCE]:
1. MC Workbench (specify defaults and motor settings from Portescap)
2. Generate LL code for STM32CubeIDE, target firmware recommended
3. start STM32Cube : nothing changed -> generate code
4. start IDE, compile, run (its being uploaded)
5. connect using Motor Pilot V1.2.12 profiler app shows up.
6. Detect pole pairs
Specification from motor manufacturer says two pole but :
I need two rotations to come back to the same orientation, after 5 'notches' in first rotation the original position is not achieved, then 6 more notches are required in a second rotation to come to close 360deg x 2, with in total 11 notches during the two full rotations.
7. Start profile
--> using 5 as well as 6 pole pairs (also tried 1,2,4,5,5.5,6 pole pairs)
---> changed Max Speed from 8k-16k in steps of 2k rpm
max current 0.8
Motor starts spinning at around 28% profiling, runs more or less smooth around 35% at 64% begins good but starts to stutter half way then shortly after error 'Firmware fault detected' Speed Feedback' is indicated.
All help is much appreciated.
Thanks a lot
Hartwig
