5. D1340, D1352, D1379 and D1380 are the settings for the start/end frequencies of CH0 ~ CH3.
The minimun frequency is 10Hz and the default is 200Hz.
6. D1343, D1353, D1381 and D1382 are the settings for the time of the first segment and the last
deceleration segment of CH0 ~ CH3. The acceleration/deceleration time cannot be shorter
than 10ms. The outptut will be operated at 10ms if the time set is less than 10ms or greater
than 10,000ms. The dafault setting is 100ms.
7. D1198, D1199, D1478 and D1479 are the output/input ratio of the close loop control in CH0 ~
CH3. K1 refers to 1 output pulse out for the 100 target feedback input pulses; K200 refers to
200 output pulses out of the 100 target feedback input pulses. D1198, D1199, D1478 and
D1479 are the numerators of the ratio (range: K1 ~ K10,000) and the denominator is fixed at
K100 (the denominator does not need to be entered).
8. M1305, M1306, M1532 and M1533 are the direction signal flags for CH0 ~ CH3. When
S
2
is a
positive value, the output will be in the forward direction and the flag will be Off. When
S
2
is a
negative value, the output will be in the reverse direction and the flag will be On.
Close Loop description:
1. Function: Immediately stop the high-speed pulse output based on the number of feedback
pulses or external interrupt signals.

3. How to adjust the time for the positioning:
a) The time for the completion of the positioning refers to the time for “accele high
speed + decele idling” (see the figure above). For example, the entire number of
output pulses can be increased or decreased by making the adjustment to the percentage
value and further increase or decrease the time required for the positioning.
b) Among the four segments of time, only the idling time cannot be adjusted directly.
However, you can determine if the execution result is good or bad by the length of the idle
time.
c) Because this is a close loop operation, the length of the idle time will not be the same for
each execution. Therefore, when the content of the D register for displaying the actual
