3.14 Simultaneously Start/Stop Signals STA and STP
(PCI-8164 only)
The PCI-8164 provides STA and STP signals that enable simulta-
neous start/stop of motions on multiple axes. The STA and STP
signals are located on CN4.
The diagram below shows the tied STA and STP signals of the
four axes.
Both STP and STA signals are input and output signals. To oper-
ate the start and stop action simultaneously, both software control
and external control are needed. With software control, the signals
can be generated from any one of the PCL6045. You can also use
an external open collector or switch to drive the STA/STP signals
for simultaneous start/stop.
If there are two or more PCI-8164 cards, cascade the CN4 con-
nectors of all cards for simultaneous start/stop control on all con-
cerned axes. In this case, connect CN4 as shown below.
The following diagram shows how to allow an external signal to ini-
tiate the simultaneous start/stop connect a 7406 (open collector)
or an equivalent circuit.
