Run on blind rotator

[TecnoTalarn]

Hi, I don't know if there is any mode of operation that can work with my rotor.
My rotor is very simple, it is a tagra 50, very old. This device has two motors, one is the rotor itself, and the other is in control. Its operation is based on the confidence that the rotor motor and the control motor work equally well.
It only has three cables, to turn the motor of the rotator CW or CCW.
It does not carry brake, and to do a position reset it is necessary to turn to the maximum cw and then cww.
I’ve been thinking of doing a command based on how long it takes to make a complete turn and with an arduino tell you how long to turn and where to do it.
It's pretty simple, and it works, but I think adding this feature to your software would give me access to other possibilities that I don't see myself able to implement in my software.
I repeat that I don't know, I haven't seen it, if there is any management for "blind" rotors, that if it were there, it would be worth it to me. If not, how can I help add this option?

Thanks,
George
