6 MULTI-PURPOSE CONTROL APPLICATION6.1 INTRODUCTIONSelect the Multi-purpose Control Application in menu M6 on page S6.2.The Multi-purpose Control application provides a wide range of parameters for controllingmotors. It can be used for various kinds of different processes, where wide flexibility of I/Osignals is needed and PID control is not necessary (if you need PID control functions, use thePID Control Application or Pump and Fan Control Application).The frequency reference can be selected e.g. from the analogue inputs, joystick control,motor potentiometer and from a mathematical function of the analogue inputs. There areparameters also for Fieldbus communication. Multi-step speeds and jogging speed can alsobe selected if digital inputs are programmed for these functions.• The digital inputs and all the outputs are freely programmable and the applicationsupports all I/O-boardsAdditional functions:• Analogue input signal range selection• Two frequency limit supervisions• Torque limit supervision• Reference limit supervision• Second ramps and S-shape ramp programming• Programmable Start/Stop and Reverse logic• DC-brake at start and stop• Three prohibit frequency areas• Programmable U/f curve and switching frequency• Autorestart• Motor thermal and stall protection: fully programmable; off, warning, fault• Motor underload protection• Input and output phase supervision• Joystick hysteresis• Sleep functionNXP functions:• Power limit functions• Different power limits for motoring and generating side• Master Follower function• Different torque limits for motoring and generating side• Cooling monitor input from heat exchange unit• Brake monitoring input and actual current monitor for immediate brake close.• Separate speed control tuning for different speeds and loads• Inching function two different references• Possibility to connect the FB Process data to any parameter and some monitoring values• Identification parameter can be adjusted manuallyVACON · 126 MULTI-PURPOSE CONTROL APPLICATION6 TEL. +358 (0)201 2121 · FAX +358 (0)201 212 205
