The VESC Hardware Version 6 shows some erratic behaviour with the saving of the Motor and App parameters from the VESC-Tool to the VESC controller.
Steps to reproduce:
- Connect VESC via USB-cable to the PC
- Start VESC-Tool (Windows 7) - Connect > OK
- Motor Settings > General > Wattage > Enter some unique value like 777
- 'Write Motor Conf' > 'MC update OK' message
- Testing: change value to 55 > Read Motor data > 777 appears again > OK
- Disconnect button > OK - disconnect USB - disconnect battery from VESC
- Reconnect VESC > 'Read Motor Conf' > 1500000 appears (default) and not 777
- Sometimes (!) the value 777 is stored, but then several other trials > Fail
Hardware / versions:
- Maytech SUPERFOC6.8 50A VESC6-based speed controlle - two VESCs with different Soft/firmware show the same bug:
- One with 4.2 firmware and 2.03 Tool
- One with 5.1 firmware and 2.06 Tool
Update - Bug report moved to Guthub: https://github.com/vedderb/vesc_tool/issues/87
This turned out to be a hardware fault of the VESC circuit - the same that likely lead to increased power consumption of 200 mA - versus 20 mA for another VESC by the same manufacturer that also works fine with saving of the parameters.
