owerFlex 7000使用6.5KV 800A/1500A的对称门极换流晶闸管(SGCT)，变频所用逆变开关器件数量比其他任何中压变频技术的器件数量都少。功率结构为无熔断器，具有电流抑制DC电抗器。其结果是更简单，牢固，可靠之产品。
PowerFlex 7000具有免传感器的直接矢量控制。免传感器的直接矢量控制对马达的磁通是测算而不是估算。如同直流驱动，马达力矩可快速改变而不影响马达磁通。此控制方式可产生较标准V/Hz型变频更优越的运行性能。对持续运行在6Hz以下的低速应用，可选用带测速反馈的完全矢量控制

●Extensive function block library, user-defined function blocks can also be added
Added to it, the macro library and graphic symbols can be customized for the user.
Blocks can create graphics and operator panels.
●Any standard can be integrated by means of GSD file import
PROFIBUS-DP and PA devices, and through user-defined pairing
dialog box to design the configuration window for these devices.
●Profibus field controller can be integrated through FDT/DTM technology

system structure
The Freelance 800F process control system is divided into operator levels
and process control level. The operator level contains controls for operation and display.
Archiving and logging, trending and alarming functions. Controller executes open loop
and closed loop control function.
Freelance 800F DigiVis Operator Level
DigiVis operator stations use PC hardware, either standard commercial
Business PCs can also be industrial-grade PCs and run on Micro-
under soft Windows operating system. DigiVis supports dual-screen display operation
operating technology, that is to say, two operations can be performed using one PC
station and operate with a
