6 MULTI-PURPOSE CONTROL APPLICATION
6.1 INTRODUCTION
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 (if you need PID control functions, use the
PID 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 are
parameters also for Fieldbus communication. Multi-step speeds and jogging speed can also
be selected if digital inputs are programmed for these functions.
•
The digital inputs and all the outputs are freely programmable and the application
supports all I/O-boards
