[Melad]

Hello, attached link represents a part of a UnityPro program controlling a packaging machine, It is required to change the direction of the film unwind motor (Axis_Ref_2) I need to add a button to select the rotation direction of the motor (FWD/REV) know that the speed reference of the altivar312 is by analog input 4-20mA (AI3) and start stop by CANOpen as you see in the attached file.
May anyone please help me to make the necessary modifications?
