Inverter operation sequence customized for the machine
Inverter control such as inverter operations triggered by input signals, signal output based on inverter operation status, and
monitor output can be freely customized based on the machine specifications. Control programs can be created in
sequence ladders using the inverter setup software (FR Configurator2) (to be supported soon). Also, the sample ladders will
be available for downloading from the Mitsubishi Electric FA Global Website.
Tension sensor feedback torque control
The control function is used for raising accuracy of the tension control using feedback from the tension detector.
PI control is used for compensating the tension value errors arising from errors with the winding diameter or mechanical loss
(caused by the temperature change / aging degradation).
Actual line speed
Motor speed
Tension feedback
Die schedule function
Combination of the dies can be
automatically changed using the PLC
function of the inverter by setting values
such as the gear ratio or the ratio
between the wire diameters at each
capstan and after the final die, and
calculating the rotation speed of each
capstan according to the material.
