7 Multi-purpose Control Application

7.1 Introduction to Multi-purpose Control Application

Select the Multi-purpose Control Application in menu M6 on page S6.2.
The Multi-purpose Control application provides a wide range of parameters for controlling motors. It can be used for various kinds
of different processes, where wide flexibility of I/O signals is needed and PID control is not necessary. When PID control functions
are needed, use the PID Control Application or Pump and Fan Control Application).
The frequency reference can be selected, for example, from the analog inputs, joystick control, motor potentiometer and from a
mathematical function of the analog inputs. There are parameters also for Fieldbus communication. If digital inputs are program-
med for multi-step speeds and jogging speed, these functions can be also selected.
• The digital inputs and all the outputs are freely programmable and the application supports all I/O-boards.
Extra functions:
• Analog 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
• Auto restart
• Motor thermal and stall protection: fully programmable; off, warning, fault
• Motor underload protection
• Input and output phase supervision
• Joystick hysteresis
• Sleep function

VACON NXP 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 manually
• Condition-based monitoring (license), see
The parameters of the Multi-purpose Control Application are explained in Chapter Parameter descriptions of this manual. The ex-
planations are arranged according to the individual ID number of the parameter.
