What is the important role when using the slitting line?

The slitting line-tension control can output a standard 0-10V analog signal, corresponding to the extra torque of the asynchronous motor. Therefore, we use the analog signal to access the inverter and select the torque reference. This ensures a constant tension throughout the dynamics of the winding.

Speed is constrained in the drive torque mode. In the tension control mode, regardless of the DC motor and the communication motor, the servo motor must be speed-constrained. Otherwise, when the torque generated by the motor can beat the load torque and run, the rotational acceleration will occur, and the rotational speed will be continuously added. The final speed to high speed is the so-called speed.

The speed of rewinding and unwinding is limited by the analog output AFM of the spindle B series inverter. It is also to set the 3-05 (analog signal output selection) parameter of the spindle B series to 03 (frequency command output). ). The signal is separately connected to the analog comfort port of the rewinding and unwinding frequency converter as a setting signal for frequency reference and sad frequency.

Slitting line - zero speed tension control requirements, when the rewinding and unwinding is running at 0 Hz, the output shaft of the motor has a certain tension output and is adjustable. The requirement is mainly to avoid parking when the rewinding and unwinding is in operation, and to ensure that the reeling of the reeling and unwinding will not be loosened when starting up. In this control system, the initial tension setting on the tension manipulator can be adjusted to meet the requirements.
