CNT32-4MT(LPCI)
Status input
The CNT32-4MT(LPCI) has the following status.
Pulse signal input states
The phase-A, phase-B, and phase-Z input states and count directions can be checked by their status.
Control input signal states
The control input signal states can be checked by the status.
Error
Abnormal input error
An abnormal input error occurs when the counter input signal changes on the A and B phases
simultaneously. A status is latched to indicate that this error has occurred and can be cleared by software.
Digital filter error
When a signal faster than the digital filter setting is input to phase-A or B, it is reported as a digital filter
error. The status is latched and cleared by software.
Carry/Borrow
Carry
The 32-bit counter is set to [1] when incremented from its maximum value FFFFFFFFh - 0h.
Borrow
The counter is set to [1] when decremented from 0h - FFFFFFFFh.
Count match
A count match (to register 0), count match (to register 1), incremental count match, or decremental count
match for each channel can be checked by the status.
