Micromaster 420, single-phase 230 V input or three-phase 440 V input. Features and Benefits: Microprocessor-controlled, utilizes IGBT technology. Easy commissioning and setup. Ready to use with factory-set default values. An optional control panel is required to change these default values. Selectable switching frequency to ensure quiet motor operation. Modular design. Programmable and scalable analog input for 0 to 10 V. Fully programmable relay output. Integrated Class A EMC filter for single-phase type. External options for PC communications, control panels, or Profibus communication module. Optional control panels for greater control, adjustment, and modification of parameters. Flux Current Control (FCC) for good dynamic response and motor control. FCL (Fast Current Limitation) for operation with a non-tripping mechanism. Integrated DC feed brake. Programmable smoothing for acceleration/deceleration times. Control loop with feedback via PI. Comprehensive range of protection features such as over-temperature protection and short-circuit protection. Manuals and software programs are provided on a CD that is only compatible with Windows NT and 2000. Application Area: Can be used for advanced motor control applications through its extensive parameter lists. Note: A control panel is required to operate this unit or to change the factory-set parameters.
