Commissioning parameters of Mitsubishi frequency converter uncoiler
The sensor adopts 0-10V three wire voltage signal, of which the terminals are 10, 5 and 4. It sends the signal to the frequency converter to control the speed of the motor and realize stable uncoiling and paying off. The uncoiler has negative effect and the winder has positive effect. The frequency converter model is fr-a740-2.2k
