Hi,
I have a problem with the configuration of the current close loop on the PowerBrickAC. We have DC (brush) motor with the next specifications:
R = 3.7 ohms
L = 2.7 mH
V = 48 VDC
We configure the motor as the manual said. To do the auto-tuning of the current close loop we blocked the motor and set the PhaseTableBias to +512, but the response did not according to the manual, and our expectations.
We read the manual of the Power Pmac to tune the current close loop, but we don't understand why the amplitud of the step test waveform is too different to the value that we set.
I attached the graph of the response and the configuration.
Thanks in advance,
Regards
Roberto
