iQ Monozukuri CONVERTING Converting Library

FA Application Package iQ Monozukuri CONVERTING

Four types of tension control

Tension sensor feedback velocity control
This converting library executes the PID control according to the value detected by the tension detector and controls the velocity so that the tension reaches the specified tension.

Tension sensor feedback velocity control

Dancer feedback velocity control
This converting library detects the position of the dancer roll and controls the velocity to reach the target position.

Dancer feedback velocity control

Tension sensor feedback torque control
This converting library performs the PID control according to the value detected by the tension detector and controls the torque so that the torque reaches the set tension value.

Tension sensor feedback torque control

Tension sensorless torque control
This converting library performs the torque control without sensors to control the tension in unwinding and rewinding.

Tension sensorless torque control

Additional functions

Tension gain auto tuning

The tension gain in tension sensor feedback control and dancer feedback control is automatically tuned.

Edge position control

Edge position of the material is detected and corrected.

●When the unwinder axis moves
   (The edge sensor position is fixed.)
●When the unwinder axis moves (The edge sensor position is fixed.)
●When the intermediate axis moves
●When the intermediate axis moves
●When the rewinder axis moves
   (The edge sensor follows the rewinder axis.)
●When the rewinder axis moves (The edge sensor follows the rewinder axis.)

Cam generation for flat roll

Flat type rewinder generates a velocity pattern (cam pattern) so that the feed speed of the material becomes constant, suppressing tension fluctuation for winding operation.
