5.2. Firmware and VESC TOOL

The MKSESC 75200 V2 requires specific firmware and VESC TOOL versions for optimal performance and compatibility.

Figure 11: Important Firmware Information

• For units purchased before November 15, 2023 (Old Version):
  • These units do not support phase filtering.
  • When using factory firmware model 75200 R2, you kudu turn off the phase filtering function (set "Enable Phase Filters" to False).
  • It is recommended to use the firmware model MKSESC_75200_V2_OLD pikeun pamakéan saterusna.
• For units purchased after November 15, 2023 (New Version):
  • These units support phase filtering.
  • The factory firmware version is V6.02, and the firmware model is MKSESC_75200_V2.

Firmware and VESC TOOL Correspondence:

Important ADC Note: ADC can only accept 3.3V signals, not 5V signals. When using any throttle handle to connect to the ADC interface, please make sure that the positive pole of the power supply is connected to 3.3V, not 5V.

6. Operasi
