Manual Pulse Generator Input Signals PA and PB
The PCIe-8154 can accept differential manual pulse generator
input signals through the pins of P1 listed below. The manual
pulse generator acts as an encoder, with A-B phase signals gen-
erating positioning information to guide the motor.
Table 2-15: Manual Pulse Generator Input Signal Connection
The manual pulse generator signals are used for axes 0 to 3,
where each axis’ manual pulse generator can be disabled with the
_8154_disable_pulser_input function.
