Product information
Product description
The MultiControl is a control for conveyor systems that can control up to four motors. At the
same time, it is also a certified I/O device for PROFINET, EtherNet/IP and EtherCAT and, as such,
can be networked with other MultiControls and a PLC.
Sensors and RollerDrive can be integrated directly into the fieldbus layer via the MultiControl.
This allows saving a complete additional sensor/actuator layer.
The MultiControl can easily and flexibly be configured via a PLC programming environment, a
web user interface or the Interroll Teach-In procedure. The procedure simplifies and shortens the
startup time on site and also enables the simple exchange of a single MultiControl.
If a special conveyor logic is to be used, the MultiControl can be equipped with a special
software by Interroll. As a result, it can be used as an individual control system – with or without
connected PLC.
The MultiControl is compatible with all 24-V conveyor modules from Interroll Automation GmbH.
So-called ZPA+ programs are used to operate the conveyor modules. These programs are
described in a separate operating manual. The functions of the ZPA programs are also
described in a separate operating manual.
Teach-In procedure
To provide an easy startup of large conveyor systems with many zones, it is possible to
automatically configure MultiControl. For this purpose, the fault signals or operational currents
of the connected motors as well as the signals of at least two adjacent zone sensors are
captured and analyzed and used to determine or specify the following settings:
• The number of motors connected to every MultiControl
• The number of zones per MultiControl
• The network address of every MultiControl
• A name assignment for every MultiControl
• The neighboring relations of the MultiControl
• Rotating direction of the motors for downstream transport
The function of the teach-in procedure is described in a separate operating manual.
Energy recovery /
Overvoltage protection
If the RollerDrive is braked or stopped, the kinetic energy of the RollerDrive (and the material
being conveyed) will be converted into electrical energy. This energy is fed back into the system
where it can be used by other RollerDrive.
If the energy recovery is higher than the energy demand the excess energy is converted into
heat by a brake chopper integrated in the MultiControl. The brake chopper is activated when
the voltage exceeds 25.2V. As such, excessively high voltages within the system are avoided.
Overload protection
device
If the brake chopper is activated for more than two seconds, it is switched off again since it is
assumed in this case that the power supply delivers an incorrect voltage. If overload protection is
active, this is shown on the LED display. As long as overload protection is active, the motors
cannot be switched on.
