a) For ELCM-PH/PA series,
M1029 = ON after Y0/Y1 (D1220=K1, pulse/Dir) is complete.
M1102 = ON after Y2/Y3 (D1221=K1, pulse/Dir) is complete.
M1029 = ON after the Y0/Y2 (D1220 = K3, CW/CCW) is complete.
b) The execution complete flag M1029, M1030, M1102, and M1103 should be manually
reset by the user program after the pulse output has completed.
c) When M1190~M1192 is ON, frequency 0.01~100Hz is available for outputs Y0~Y3.
d) When the PLSY / DPLSY instruction is OFF, the pulse output complete flags will all be
reset.
e) When M1190~M1192 = ON, the available output range for PLSY Y0~Y3 is 0.01~100Hz.
5. While the PLSY instruction is being executed, the output will not be affected if

is changed.
To change the number of pulses, stop the PLSY instruction, then change the number of
pulses.
6.

the pulse output frequency can be changed while the PLSY instruction is being executed.
7. The pulses sent out by the PLSY instruction are sent at a 50% duty cycle. For example, if each
pulse is sent at 1000Hz, it will be On for .5ms and Off for .5ms.
8. If operand

use the index register F, only the 16-bit instruction (PLSY) is available.
9. For ELCM-PH/PA series, there is no limit on the number of times this instruction can be used
in the program. However the program only allows 4 pulse output instructions (PLSY, PWM,
PLSR) to be executed at the same time. If Y1 is used for several high speed pulse output
instructions, the controller will execute each one in the order they are enabled and scanned in
the program.
Program Example:
1. When X0=ON, 200 pulses will be sent out Y0 at 1KHz. When the instruction is finished,
M1029=ON (the complete flag) which will turn on Y20.
2. When X0=OFF, the pulse output to Y0 will immediately stop. When X0 turns ON again, the
pulse output will restart.
