Features

• Micromaster 420,1-phase 230V input or 3-phase 440V input. Features and Benefits. Micro processor controlled, using IGBT technology. Simple to commission ; set up. Works straight from the box, using factory set defaults. To change these defaults an optional operator panel is required. Selectable switching frequency to enable quiet motor operation. Modular design. Programmable ; scalable analogue input 0 to 10V. Fully programmable relay output. Integral class A EMC filter for single phase type. External options for PC communications, operator panels or Profibus communications module. Optional operational panels for greater control, parameter setting/changing. Flux current control (FCC) for good dynamic response ; motor control. Fast current limitation (FCL) for operation with trip-free mechanism. Built in d.c. injection brake. Acceleration/deceleration times with programmable smoothing. Closed-loop control using PI. Comprehensive range of protection functions e.g. over temperature, short circuit. The instructions and software utilities are supplied on a CD compatible with Windows NT and 2000 only. Applications. Can be used for advanced motor control applications via its comprehensive parameter lists. Note: An operator panel will be required to operate this unit or to modify the factory set parameters.
