6. VACON 20 APPLICATION INTERFACE
6.1 Introduction
There is only one version of Control Board available for the Vacon 20 drive:
This section provides you with a description of the I / O-signals for Vacon 20 and in-
structions for using the Vacon 20 general purpose application.
The frequency reference can be selected from Preset Speed 0, Keypad, Fieldbus,
AI1, AI2, AI1+AI2, PID, Motor potentiometer and Pulse train / Encoder.
Basic properties:
• Digital inputs DI1…DI6 are freely programmable. The user can assign a
single input to many functions.
• Digital-, relay- and analogue outputs are freely programmable.
• Analog output can be programmed as current or voltage output.
• Analog input 1 can be as voltage input,analog input 2 can be
programmed as current or voltage input.
• DI5/6 can be used as pulse train or Encoder.
Special features:
• Programmable Start / Stop and Reverse signal logic
• Motor pre-heat
• Reference scaling
• DC-brake at start and stop
• Programmable U / f curve
• Adjustable switching frequency
• Autoreset function after fault
