Simultaneous Start/Stop Signals STA and STP
The PCIe-8154 provides STA and STP signals, which enable
simultaneous starting and stopping of motion on multiple axes.
The STA and STP signals are on K1/K2.
The STP and STA signals are both input and output signals. To
start and stop simultaneously, both software control and external
control are needed. With software control, the signals can be gen-
erated from any connected PCIe-8154. Alternatively, an external
open collector or switch can drive the STA/STP signals for simul-
taneous start and stop.
If there are two or more PCIe-8154 cards, connect the K2 connec-
tor on the previous card to K1 connector on the next card. K1 and
K2 connectors on the same PCIe-8154 are connected internally.
