Product information
Functions
• The speed and direction of rotation of a RollerDrive EC310 (or EC300 with adapter cable) can be controlled.
• The signals from two sensors (start and zone sensors) can be evaluated.
• The feeding of packages into the start zone can be controlled by a sensor or by an external signal.
• Transport logic can be influenced by external control signals (ZONE_START, ZONE_STOP, ZONE_STATUS, CLEAR,
DIR_RET), enabling different functions:
- Automatic stop at personal gates
- Individual zone stops within the conveyor line
- Clearing the entire system in or against the set direction of rotation
- Feed-in/removal of packages outside of the start and end zone (for instance in conjunction with an external
handling system)
• The control signals can either be processed in PNP mode or in NPN mode.
• Regenerative braking: When the RollerDrive motor brakes, it acts as a generator and feeds energy back into the
power supply. The ZoneControl is fitted with a brake chopper.
Speed settings
The speed of the RollerDrive can be adjusted in two different ways by ZoneControl:
• Internally at eight levels by means of three DIP switches
• Externally continuously via the analog input SPEED (is handled with priority and enables more fine-tuned
adjustment)
The speed setting is converted to an analog control voltage by the ZoneControl and output by the RollerDrive as a
reference setting. This reference setting is independent of the RollerDrive gears and their diameter.
Speed setting of the see „Speed setting”, page 40.
The acceleration and braking behaviour of the RollerDrive is defined by its own moment of inertia, the gears used, the
conveying speed, the moment of inertia of connected conveyor rollers, the selected torque transmission and the goods
transported.
Feedback of energy / Overvoltage protection
If the RollerDrive is stopped by the ZoneControl or if the speed is reduced abruptly, the kinetic energy of the package
is regeneratively converted into electrical energy in the motor. This energy is then fed back into the ZoneControl,
resulting in increased voltage in the DC-net. This is limited to a non-critical level (28 V) by the integral brake chopper.
However, if there are enough other consumers attached to the DC-net, the voltage rise will be low and the energy
will be fed back in, resulting in the energy being available to other consumers in the DC-net and energy-savings being
made if conditions are favourable.
