Hello,

are you planning to use the SIMATIC library LCon to control the two winders or are you planning to run it in the drive?

For SIMATIC it depends on your control mode (torque or speed controlled) and the type of controller (S7-1200 without technology objects /  S7-1500 using technology objects).
