8. D1131 and D1132 are the output/input ratio(%) of the close loop control in CH0 and CH1. K1
refers to 1 output pulse out of 100 feedback pulses; K200 refers to 200 output pulses out of
the 100 feedback pulses. In the general percentage equation, the value set in D1131 and
D1132 represents numerators (output pulses, available range: K1 ~ K10,000) and the
denominator (the input feedbacks) is fixed at K100.
9. M1305 and M1306 can reverse the direction of CH0, CH1 pulse output. For example, when
direction signal output (Y1/Y3) is OFF, the pulse output will operate in positive direction. If
M1305/M1306 is set ON before the execution of this instruction, the pulse output will operate in
the reverse direction.
10. When
S
1
designates input points X with interrupt pointers, D1244 / D1255 can be used for
setting the idle time to limited the number of pulses, in case the interrupt is not properly
triggered.
11. DCLLM instruction supports the Alignment Mark and Mask function. The
Points to note
below
provide more details.
Program Example3:
Immediately stop the high-speed pulse output with an external interrupt
1. X4 is used as the input for the external interrupt and I401 (rising-edge trigger) as the interrupt
pointer. Set the target number of feedbacks = 50,000; target frequency = 100kHz; pulse output
address: Y0, Y1 (CH0); start/end frequency (D1340) = 100Hz; ramp-up time (D1343) = 100ms;
ramp-down time (D1348) = 100ms; percentage value (D1131) = 100; present value of output
pulses (D1030, D1031) = 0.
