Manual
– ECC-DFC field bus controller
5.2. Example 2
– Single-zone controller
In this example, a single motor roller and a single photo sensor are connected to
either the left or right interface area. The module controls the motor roller as an
individual, independent logical conveyor belt zone.
5.3. Example 3
– Double-motor-roller, single-zone control
In this case, the module will control 2 motor rollers together and operate them as
a single zone with a single photo sensor, which is connected to either the left or
right connector. This configuration is typical especially for inclined conveyor belt
zones, since inclined conveyors need the additional torque of a second motor
roller to transport loads.
5.4. Examples of invalid configuration
Since the auto configuration of the ECC-DFC is determined by how the photo
sensors are connected, it is possible to connect photo sensors and motor rollers
in the wrong way, which can lead to unexpected results.
In these cases, the module will attempt to operate as a single-zone controller, but
the motor rollers are not connected to the same left/right interface area as the
photo sensors.
