Signal Connections
The diagram below shows the onboard circuit. The STA and STP
signals of the two axes are tied together respectively.
The STP and STA signals are both input and output signals. To
operate 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 PCI-8102. Users
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-8102 cards, connect the K2 connector
on the previous card to K1 connector on the following card. The
K1 and K2 connectors on a same PCI-8102 are connected inter-
nally.
User can also use external start and stop signals to issue a cross-
card simultaneous motor operation. Just connect external start
and stop signals to STA and STP pins on the K1 connector of the
first PCI-8102 card.
