3.12 Multi-Functional Input Pin: LTC/SD/PCS/CLR
The PCI-8102 provides 2 multi-functional input pins. Each of the 2
pins can be configured either as LTC(Latch) or SD(Slow down) or
PCS(Target position override) or CLR(Counter clear). To select the
pin function, please refer to 6.12. The default value is LTC and the
relavant functions are as follows:
I16 _8102_select_pin23_input(I16 card_id, U16 Select );
I16 _8102_select_pin57_input(I16 card_id, U16 Select );
The multi-functional input pins are on P1. The signal names, pin
numbers, and axis numbers are shown as follows:
The multi-functional input pin wiring diagram is as followed:
3.13 Simultaneously Start/Stop Signals STA and STP
