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

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.
