Does anyone know anything about the note Flipsky recently posted on their website regarding the prohibition on enabling phase filtering?
Phase filtering is not available for Flipsky ESC75100 and 75200!
Please turn off the phase filter function and choose "false" in vesc_tool when use firmware version on or above 5.3 (VESC_TOOL 3.01). Without turning off the phase filter will result in esc damage. Please do not restore the default parameters when using the wizard interface.
So far, my email to Flipsky has gone unanswered. Some of my observations:
The phase filtering configuration parameter is prefixed by FOC. Is it only applicable to FOC mode?
It is enabled by default in both VESC Tool 3.0 and 3.01.
Judging by the VESC_75_300 schematic, it appears an analog switch (MC74HCV1GT66) is used to enable a simple RC lowpass filter (1k ohm x 15nF) for each of the phase current measurements.
I don't see these switches present on the FSESC75200.
