Pouch machine

To improve the production of metal wire processing, quality and cost reduction, wire drawing machine generally to frequency conversion constant tension control, and most current frequency conversion synchronous control is usually USES the external control method of PID controller, the disadvantage of this approach are: the control of the PID controller parameter debugging difficulty, PID response speed slow, causing tension rocker bobbing in the big, in this way, will inevitably affect the quality of metal wire processing, which is currently many inverter in the wire drawing machine are widespread and difficult to solve the problem.

At present, wire drawing machine using inverter for constant tension control has been a development trend, general requirements inverter contains PID rapid adjustment function, at present in the industry application, only a few brands of inverter can not add any auxiliary accessories to achieve such a requirement.
