Product Description
2.2.6
Direct Control
In this operating mode, the DC roller motors connected to the ZPA motor control module can be
controlled using external signals. In this way, the ZPA control module can, for example, be
connected directly to a PLC that follows its own logic for controlling the DC roller motors. The
control signals are transferred via the inputs of the respective zone coupling interfaces. The
outputs of the two zone coupling interfaces indicate the status of the zone sensors.
2.2.7
Direction Control
This operating mode supplements the "Direct Control" operating mode with the option of
reversing the direction of rotation of the connected DC roller motors via an external signal. One
input controls both DC motor rollers while the other input reverses their configured direction of
rotation.
The "Direction Control" operating mode will be supported from firmware version V.26.
