Thank you Neale,
The sensorless parameter in VFD is "Ctt [Motor control type] - uuC (Sensorless vector control)", in last configuration I tried to use "Ctt [Motor control type] - set to Std (Standard motor)". But will make a change and will come back with results :)
DI1 and DI2 is set to be Forward and reverse inputs, I will double check if there is anything to configure further, once I will be back from work.
Very good eye Neale on noticing output activation - fantastic :) that explains why in some case spindle rotation dir is unpredictable :). Thing is that I can't have separate pin output for FWD / REV as in UCCNC, if PWM spindle control mode is selected - only PWM control pin and DIR pin are available to set (can't choose FWD / REV pins). Maybe I should go with relay control for FWD / REV functions, in that case, two separate PIN's can be chosen.
Will tryout and will be back with results :)
Thanx ! :)
