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
