output will stop after 1,000,000 pulses are completed.
• When pulse output ramps down and stops after Mark is detected, M1538 will be ON to
indicate the pause status. If users need to complete the remaining pulses, set OFF the
flag M1108 and pulse output will resume.

• Mask function on Y0 will be enabled when D1026 and D1027 are specified with values other
than 0. Mask function is disabled when D1026 and D1027 are specified with 0. If pulse output
process can not reach the target speed, PLC will clear DD1026 to disable the Mask function. If
the Mask range is set to be within the ramp-up section, PLC will automatically modify DD1026
to be longer than the ramp-up section. On the other hand, if DD1026 is set between rampdown
section, PLC will modify DD1026 to be the range before the beginning of ramp-down
process. Mask function setting method on Y2 is the same as Y0.
