Note IN0 through IN3 can be set for use as input interrupts in the PC Setup. The ON
and OFF delays for input interrupts are fixed at 0.1 ms max. and 0.5 ms max.,
respectively. IN4 through IN6 can be set for use as high-speed counter inter-
rupts. The delays for high-speed counter interrupts are shown in the following
table.
Input Increment input mode Differential phase mode
IN4 (A) 5 KHz
2.5 KHz
IN5 (B) Normal input
IN6 (Z) ON: 100 ms min. required; OFF delay: 500 ms min. required
