D1235:  Output pulse number for ramp-down stop when Y2 mark sensor receives signals 
(High word). 
D1348:  M
1534 = 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
3 
and ramp down time in D1348/D1349. (Range: 20ms~32767ms)   
  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.   
  Ramp-down stop pulses (DD1232/DD1234) are 32-bit value. Set value K0 will disable the 
Mark function.
