Chapter 7 Option Cards | VFD-ED
When OUT/M, IN/M set to 0 and 0, the PG card input signal A-/A, B-/B are square waves while AO-
, BO-
are frequency division output.
When OUT/M, IN/M are set to 1 and 0, the PG card input signal A-/A, B-/B are square waves while the
BO-
is the A and B phase indicator (for example, when
BO-
is LOW, it means A is ahead of B:
when
BO-
is HIGH, it means B is ahead of A).
AO-
is frequency division output.
When OUT/M, IN/M are set to X and 1, B-/B phase has to be the direction indication input signal (for
example, when B-/B is LOW, it means A is ahead of B; when B-/B is HIGH, it means B is ahead of A).
A-/A is a square wave input, BO-
and B-/B phase are input into synchronous action;
AO-
is
frequency division output.
Take Pr.10-29 and Pr.10-30 as examples: When the frequency division value is 15, OUT/M =1, IN/M =
0. Set Pr.10-29 = 15 and Pr.10-30 = 0002h.
Set Pr.10-29 =15
Set Pr.10-30 =0002h
