the pulse output frequency can be changed while the PLSY instruction is being executed.
14. 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.
15. If operands

,
S
2
use index register F, then only the 16-bit instruction is available (PLSY).
16. For ELC-PB, ELCB-PB series, the PLSY instruction can only be used twice in the program.
17. For ELC-PC/PA/PH/PV series, there is no limit on the number of times this instruction may be
used in the program. However, for the ELC-PC/PA series, the program only allows two PLSY
instructions to be executed at the same time. For ELC-PH/PV series, the program allows four
PLSY instructions to be executed at the same time.
ELCM-PH/PA Controllers
1.
S
1
specifies the pulse output frequency
Output frequency range
Output Y0, Y2 Y1, Y3
16-bit instruction 0~32,767 Hz 0~10,000Hz range
32-bit instruction 0~100,000Hz 0~10,000Hz
If 0Hz is specified, pulse output will be disabled
2.
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 continuous output.
3. ELCM-PH/PA series have four pulse output modes as shown below.
D1220 D1221
