It is understood, leather machinery slitting machine in practical work applications to join frequency converter has become increasingly popular because they drive on the device played a good supporting role, such as when the AC induction motor characteristics well, activation switch torque is low and nonlinear therefore winding the entire process to try to avoid winding motor operates at 2hz below, to ensure there is a winding motor minimum speed limit. The device can also be achieved so speed operation effect.
Then, the drive leather machinery slitting machine is how it works, it completed its functional role, the following will be discussed in detail:
Frequency converter in constant tension control system works
For the process of unwinding and rewinding tension control needs to know the essence of the load during operation roll diameter changes, because changes that lead to the load in order to maintain the operation of the motor output torque required to keep track with the volume and change. The drive torque control can be done, it is also able to complete the winding constant tension control. Inverter provides three analog input ports. Three-channel analog input port can be defined as a variety of functions, therefore, you can choose the way as the torque reference, as another way to speed limits. For slitting machine, roll diameter calculated in part by tension controller to be calculated. In other words, you can set on the HMI or text tension, roll diameter calculated through plc, you can calculate the size required motor output torque, through the analog output to the torque given Ambition Inverter end, or available.
