Undervoltage Fault

Can someone point me in the right direction to start troubleshooting undervoltage fault code?

I get the motor spinning with remote but intermittent fault codes. Not using a BMS.

Motor:              Brushless  Filipsky 65161 100KV
Input PWM:       Maytech Eskate Remote VESC MTSKR2005WF V2
ESC:                 Firduo HL200 75V 200A ESC
Vesc tool:         version 3.01
Configs:           Ran motor and input wizard (PWM Current no reverse with break), adjusted motor poles to 6, set battery cutoffs for 14s9p lipo

The following faults were registered since start:

 

Fault : FAULT_CODE_UNDER_VOLTAGE

Motor : 1

Current : -0.0

Current filtered : -0.2

Voltage : 1.82

Аналогичная проблема на одном из моторов. Использую ubox dual v2 100*200, firmware 5.3

Решения так и не нашел кроме как настроить на игнорирование данной ошибки.

Thank you for your response. My undervoltage fault has gone away and my motor is operating much better. If I can understand what initial settings I had that caused it, I will repost to this thread.  Cheers.

Благодарю за ваш ответ. Моя ошибка пониженного напряжения исчезла, и мой двигатель работает намного лучше. Если я смогу понять, какие первоначальные настройки вызвали это, я опубликую сообщение в этой теме. Ваше здоровье.

Did you figure out what the problem was? If not, how did you program it to stop causing the fault? I have this issue when coming to a stop and then hitting pedal to go again... Thanks!
