Analogue Extension Module

Chapter overview

The chapter describes the use of analogue extension module RAIO as the speed
reference interface of an ACS800 drive equipped with the Crane control program.

Speed control through the analogue extension module

Two variants are described:
• Bipolar Input in Basic Speed Control
• Bipolar Input in Joystick Mode
Only the use of a bipolar input (± signal range) is covered here. The use of unipolar
input corresponds to that of a standard unipolar input when:
• the settings described below are done, and
• the communication between the module and the drive is activated with parameter
98.06

Basic checks

Ensure the drive is:
• installed and commissioned, and
• the external start and stop signals are connected.
Ensure the extension module:
• settings are adjusted. (See below.)
• is installed and reference signal is connected to AI1.
• is connected to the drive.

Settings of the analogue extension module and the drive

• Set the module node address to 5 (not required if installed to the option slot of the
drive).
• Select the signal type for the module input AI1 (switch).
• Select the operation mode (unipolar/bipolar) of the module input (switch).
• Ensure the drive parameter settings correspond to the mode of the module inputs
(parameter
• Set the drive parameters (see the appropriate section on the following pages).
