Application of KE300A-10 inverter in wire drawing machine

High-speed wire drawing machine is one of the main equipment of metal wire processing, mainly is the metal wire processing into various specifications of fine wire. From the product specifications to distinguish the wire drawing machine can be divided into large pull machine, middle pull machine, small pull machine, micro pull machine; From the production process can be divided into water tank type, roller type, straight into the main several.

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 are 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 VFD solar inverters 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.
