12.8 PLSY / Pulse Y Output
2. Frequency
When using transistor outputs in the main unit, set the output frequency specified by as follows.
Do not set the frequency to "0".
•FX
3U and FX3UC PLCs : 16-bit instruction→1 to 32,767Hz
32-bit instruction→1 to 200,000Hz (
When using special high speed output
adapter)
→1 to 100,000Hz (
When using main unit)
•FX3S, FX3G and FX3GC PLCs : 16-bit instruction→1 to 32,767Hz
32-bit instruction→1 to 100,000Hz
•FX
2N and FX2NC PLCs : 2 to 20,000Hz
•FX
1NC PLC : 1 to 10,000Hz
•FX
1S and FX1N PLCs : 16-bit instruction→1 to 32,767Hz
32-bit instruction→1 to 100,000Hz
•FX
0S, FX0 and FX0N PLCs : 10 to 2,000Hz
•FX
U and FX2C PLCs : 1 to 1,000Hz
3. Pulse quantity
The pulse quantity can be set in the range from 1 to 32,767 (PLS) for 16-bit instructions and from 1 to
2,147,483,647 (PLS) for 32-bit instructions. If set to zero, pulse generates infinitely.
4. Pulse output
1) Only a transistor output on the main unit or the following special high speed output adapters
*1
can be
specified in .
•FX
3S, FX3G, FX3GC, FX3U and FX3UC PLCs : Y000, Y001
•FX
1S, FX1N, FX1NC, FX2N and FX2NC PLCs : Y000, Y001
•FX
0S, FX0 and FX0N PLCs : Y000
•FX
U and FX2C PLCs : Valid for all Y
When using the PLSY instruction with a relay output type or triac output type FX
3U PLC, a special
highspeed output adapter is required.
*1. Special high speed output adapters can be connected only to the FX
3U PLC.
2) The duty cycle of the pulse ON/OFF time is 50 % inside the PLC.
However, 50 % may not be output depending on the frequency due to the effect of the output circuit.
3) The pulse output is controlled by the dedicated hardware not affected by the sequence program
(operation cycle).
4) If the command input is set to OFF during continuous pulse output, the output from the device specified
by turns OFF.
5. Restrictions to target devices
S1: Refer to item 4 of "Cautions".
S2: The FX
3G, FX3GC, FX3U and FX3UC PLCs only are applicable.
S3: The FX
3U and FX3UC PLCs only are applicable.
(Special high speed output adapters can be connected only to the FX
3U PLC.)
