3. Instruction Set
6. Pulse output flags:
M1078 M1079 M1104 M1105
a) M1029 = ON after Y0/Y1 (D1220=K1, pulse/Dir) output is completed.
M1102 = ON after Y2/Y3 (D1221=K1, pulse/Dir) output is completed.
M1029 = ON after the Y0/Y2 (D1220 = K3, CW/CCW) output is completed.
b) The execution completed flag M1029, M1030, M1102, and M1103 should be manually reset
by users after pulse output is completed.
c) When PLSY / DPLSY instruction is OFF, the pulse output completed flags will all be reset.
d) When M1190~M1193 = ON, the available output range for PLSY Y0~Y3 is 0.01~10Hz.
7. While the PLSY instruction is being executed, the output will not be affected if S
2
is changed. To
change the pulse output number, stop the PLSY instruction, then change the pulse number.
8. S
1
can be changed during program execution and the change will take effects until the modified
PLSY instruction is being executed.
9. The ratio of OFF time and ON time of the pulse output is 1:1.
10. If operand S
1
, S
2
use index F, only 16-bit instruction is available.
11. There is no limitation on the times of using this instruction, however the program allows only 4
instructions (PLSY, PWM, PLSR) to be executed at the same time. If Y1 is used for several high
speed pulse output instructions, PLC will output according to the execution order of these
instructions.
(For EC5 Series PLC CPU)
1. When PLSY instruction has been executed, the specified quantity of pulses S
2
will be output
through the pulse output device D at the specified pulse output frequency S
1
2. S
1
specifies the pulse output frequency
Output frequency range of EC5 Series PLC CPU
range
32-bit instruction 0~50,000 Hz
If frequency equals or smaller than 0Hz is specified, pulse output will be disabled.
If frequency bigger than max frequency is specified, PLC will output with max frequency.
3. S
2
specifies the number of output pulses.
16-bit instruction: -32,768~32,767. 32-bit instruction: -2,147,483,648~2,147,483,647.
When S
2
is specified as K0, the pulse will be output continuously regardless of the limit of pulse
number.
