I am receiving these error codes. I have run my 80mm spindle a few times. The only changes I have made were to reflash my buildbotics drive (non-relevant) in hopes of fixing my modbus connection…didn’t work. I am not an electrician and am not certain where to even begin when it comes to checking voltage on this vfd. I have a multimeter and understand how to use that. I’m not sure where to start here because the power sources haven’t been changed and these error codes are now appearing. Any help would be greatly appreciated. 80 mm spindle.
