Slave
In this operating mode, the ZPA motor control module functions as a slave to a downstream
master zone. Both slave motors are synchronized to the master zone motors. The master zone
is extended by the slave. The signals from the rear zone coupling of the master are transmitted
by the slave through to the upstream zone. The zone sensors of the slaves have no function in
this operating mode and do not need to be connected.
As the master, all of the ZPA motor control module operating modes can be used, except for
"Direct Control" and "Direction Control." No special settings are required at the master. As soon
as the upstream ZPA motor control module has been configured as a slave, the switchover to
master operation occurs automatically.
Any number of slaves can be run on a master zone. Each slave corresponds to a ZPA motor
control module. The zone length, which is controlled by the master, is extended by the
connected slaves. The following time conditions for the master and the connected slaves are
added up. Up to four slaves can be taken into account.
1. Search time
2. Transportation time
3. Idle mode delay
Figure 2.11
Please note that the zone couplings between master and slave work in master-slave operation.
There, there are no PLC-compatible zone coupling signals. If the zone coupling of a slave has
not been connected to a compatible master, the corresponding LED flashes "X1 IN" or "X2 IN"
and the ZPA motor control module has no function.
The "Slave" operating mode is supported from firmware version V.28 (master and slave).
