LOW means A leads B and HIGH means B leads A). A/O-/A/O is the output of
frequency divider.
When PIN 2 is set to 1 and PIN 3 is set to X, B-/B should be the input signal of
direction indication. (EX: when B-/B is LOW, it means that A leads B. When B-/B is
HIGH, it means that B leads A. A-/A is a square wave input. B/O-/B/O and B-/B
should be input synchronously.
A/O-/A/O is the output of frequency divider.
Z/O-/Z/O of the PG card will act by the input signal of Z-/Z and don’t have the
function of frequency divider.
When changing the denominator of the frequency divider or input/output type, it
needs to clear the counter value by clock reset bit (PIN4) before operation. Please
set the switch to 1 after reset.

1.
If the encoder type is line driver, the PG card will only 12V signal. Set switch
SW2 to EXT24V.
