Hello Louis, all our winder applications (Simatic, Simotion and Sinamics DCC) have the V-constant control mode. It is exactly what you require. The web speed (from tachometer running on the material) and the winder shaft actual speed are used to calculate the diameter. The material web velocity setpoint is then divided by the diameter to calculate the required winder shaft speed. Attached the general description of this mode.

New question published by lmoreschi is split to a separate thread with the subject Switch the control mode on Simotion winder axis between V-constant to indirect tension control. Best regards |
