D1232:
The number of output pulses for ramp-down stop when Y0 mark sensor receives
signals. (LOW WORD).
D1233:
The number of output pulses for ramp-down stop when Y0 mark sensor receives
signals. (HIGH WORD).
D1234:
The number of output pulses for ramp-down stop when Y2 mark sensor receives
signals (LOW WORD).
D1235:
The number of output pulses for ramp-down stop when Y2 mark sensor receives
signals (HIGH WORD).
D1348:
M1534 = ON, D1348 stores the ramp-down time of the CH0(Y0, Y1) pulse output.
D1349:
M1535 = ON, D1349 stores the ramp-down time of the 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)

a)
When M1156 = ON, enable ramp-down pause on Y0 when X4 receives interrupt signal.
b)
When Mark function is enabled, ramp down time is independent of the ramp up time.
Users can set the ramp up time in
S
3
and ramp down time in D1348. (Range:
20ms~32767ms)
c)
When the PLSR instruction is executed, the ELC will automatically calculate the
minimum pulse number required for ramp down when Mark is detected, and store the
number of pulses in D1232~D1233
d)
The number of ramp down pulses for the Mark function can be specified by users.
However, the specified number should be more than the number the ELC calculated for
the ramp-down time, otherwise the ELC will fill D1232~D1233 with the minimum Number
of pulses.
