PAR_32 7320 EncDivFilter Encoder Division Output Filter 0 ~ 15 0
Encoder division output option card outputs one pulse signal when input pulse number matches the value set in PAR_31.
A/B pulse output follows input pulse phase. The relationship between output of A, B pulse follows the same as input
pulse. Division ration can be set within the range of 1 (1 output pulse per 1 input pulse) ~ 1/128(1 output pulse to 128
input pulse).
PAR_31 setting range: 0001 ~ 1128. Division ratio cannot be set higher than 1 and only 1 or 2 can be set for
numerator. The below is Division ratio calculation formula.
N refers to the value from thousand (0000) and M refers to value less than thousand (0000)
PAR_31 set value = N×1000 + M.
Division ratio = (1+N)/M
Setting range: N (0, 1), M (1 ~ 128)
PAR_31 = [] [] [] []
When PAR_31 setting value is below 1000 (N=0), a numerator value becomes 1 and when above 1000
(N=1), a numerator value becomes 2. For example, if PAR_31 is set to 15, the division ratio is 1/15 and if
1015, the ratio is 2/15. Division ratio is settable up to 1/128 and greater than 1 is not settable. Using Up key
on the keypad PAR_31 value is increased and increase routine is 1 → 2 → 3 → 4 → … → 127 →
128(Division ratio: 1/128) → 1002 (Division ratio: 1) → 1003 → … → 1128 (Division ratio: 1/64) and
decrease routine (using Down key on the keypad) is the same as increase routine.
