Just to add, you could also use the available data logging/data storage function for monitoring the motor currents.
It's not very flexible, just frequency really, just select what you want, start it, stop it, save it (which creates a .csv file).
I've never dived deep into using it though, in terms of saving and externally sending the file (may require a purchasable option.
May be worth exploring this option, as a 'ready' to go option.
Thank You. I've already tried this but it is not solution for me.
I will prepare a client script of robot and post it here for checking. So i will be very pleased if You or colleagues will help me with advice or error founding in it.
