Since the ZPA motor control module can control two consecutive zones simultaneously, the
zone coupling of these two zones is performed internally. The zone coupling to the upstream
and downstream zones is routed via connections X1 and X2.

Operating Modes of the ZPA Motor Control Module
2.2.1
Overview
The ZPA motor control module has multiple operating modes that realize different
accumulation conveyor logics. All operate zone coupling as per the preceding description and
are therefore fully compatible with each other. The only exception to this rule are the two
operating modes "direct control" and "direction control." These operating modes do not
execute logic and are used for direct control of the connected DC roller motors via the zone
coupling interfaces.
For the operation of only one zone, the mode for 1-zone operation must be selected in the case
of some operating modes. Different time conditions detect accumulations on the conveyor line
and shut down the DC roller motors if one or more conveyed products are stuck. All operating
modes support the handling of conveyed product that is longer than the actual zone.
