3. Instruction Set

3-149

 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

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.

Explanations:

 When M0 is triggered, Y0 executes pulse output. If external interrupt is detected on X4,

pulse output will perform ramp down process for 10,000 pulses and then stop. M1108 will

be ON to indicate the pause status (ramp down). If no interrupt is detected, Y0 pulse
