High-level functional units are available for applications such as valve control or group control
of motors. The built-in features in one of the complex motor controllers, the functional unit
MOTCON, are:
• Supervision of control circuits
• Evaluation of interlocking
• Control of on/off
• Supervision of motor current
• Running of tests from the motor site
• Control from central/local operator’s station
• Manual/Auto running
• Forward/Reverse running or selection of High/Low speed.
• Presentation of Motor/MCU diagnostics (MOTCONI).
The functional unit MOTCONI has the same functionality as MOTCON. The difference is that
MOTCONI controls INSUM Motor Control Units (MCU) over the LONWORKS Network.

For large control systems, built on Advant Controller 450, the connection to ACS 600 drive
systems is made via Advant Fieldbus 100. Each fieldbus node connects up to 24 drives through
an optical ring.
Information from the drives:
Process values are sent as cyclic data, with an updating frequency decided by the
application engineer. The data enables the control system to have access to basic
information such as speed, current, torque and diagnostic information.
Information from the controller:
A set point for speed or torque in percentage or absolute values can be sent. It is also
possible to give commands to the drive, for example, start, stop and fault reset.
The operator support in AdvaCommand includes a number of drive specific displays and
dialogs as well as the possibility to use functions such as system status, alarm and event
handling and trend curves.
In order to minimize engineering efforts, a predefined type circuit is offered. It consists of
control logic for a drive in a system with Advant Controller 450.
