2. Description on associated special registers:
For D1030-D1033, D1336-D1339, D1220, D1221, please refer to PLSY instruction
D1026: M1156 = ON, D1026 stores pulse number for masking Y0 (Low word).
D1027: M1156 = ON, D1026 stores pulse number for masking Y0 (High word).
D1135: M1158 = ON, D1135 stores pulse number for masking Y2 (Low word).
D1136: M1158 = ON, D1135 stores pulse number for masking Y2 (High word).
D1232: Output pulse number for ramp-down stop when Y0 mark sensor receives signals.
(Low word).
D1233: Output pulse number for ramp-down stop when Y0 mark sensor receives signals.
(High word).
D1234: Output pulse number for ramp-down stop when Y2 mark sensor receives signals
(Low word).
D1235: Output pulse number for ramp-down stop when Y2 mark sensor receives signals
(High word).
D1348: M1534 = ON, D1348 stores the ramp-down time of CH0(Y0, Y1) pulse output.
D1349: M1535 = ON, D1349 stores the ramp-down time of CH1(Y2, Y3) pulse output.
D1340 Start/end frequency of the pulse output CH0 (Y0, Y1)
D1352 Start/end frequency of the pulse output CH1 (Y2, Y3)

When M1156/M1158 = ON, enable ramp-down pause (Mark function) on Y0/Y2 when

X4/X6 receives interrupt signals.
When Mark function is enabled, ramp down time is independent of the ramp up time. Users

can set ramp up time in S
When Mark function is executed and the ramp-down stop pulses (DD1232/DD1234) are

specified, PLC will execute ramp-down stop with specified pulses after Mark is detected.
However, if DD1232/DD1234 are less than the specified ramp-down time (D1348 / D1349),
PLC will fill DD1232/DD1234 with the value of ramp-down time. In addition, if
DD1232/DD1234 is more than the half of total output pulses, PLC will modify
DD1232/DD1234 to be less than half of the total output pulses.
