Dear Community
We are trying to get the TAPAS board up and running with a Raspberry Pi. We have tried with a 750W and a 150W BLDC.
When identifying the BLDC at the end of flux measurement, the engine brakes abruptly to zero speed. (see p.249, User's guide InstaSPIN-FOC & InstaSPIN-Motion)
The program changes to the idel state without first making the Ls measurement and all values already measured are reset to zero. The identification of the engine can therefore not be completed or it sets an overcurrent error.
Before Rated_Flux State the program is in Rated_Flux_ol. Therefore, we exclude that an 'ACIM machine' is set as default and a lock_rotor is set.
the following attempts have already been made:
- Parallel switching of power resistors when feeding the TAPAS to intercept feedback (Overcurrent_Error)
- DC power supply between 10 and 30V.
- Different motor maximum currents between 10 and 50A (750W BLDC) / 5 and 15A (150W BLDC).
- Different fluxEstFrequency between 10 and 100Hz in 10Hz steps (see p.300, user's guide InstaSPIN- FOC & InstaSPIN-Motion)
Thanks for any feedback
With kind regards
