12.10 PLSR / Acceleration/Deceleration Setup
•For FX3U and FX3UC PLCs :16-bit instruction→10 to 32,767(Hz)
32-bit instruction→10 to 100,000 Hz or less
(200,000 Hz or less when using special high speed adapter.)
•For FX3S, FX3G and FX3GC PLCs :16-bit instruction→10 to 32,767(Hz)
32-bit instruction→10 to 100,000 Hz or less
•For FX
2N and FX2NC PLCs :10 to 20,000 Hz
•For FX
1S and FX1N PLC :10 to 100,000 Hz
•For FX
1NC PLC :10 to 10,000 Hz
2. Total number of output pulses
Set the total number of output pulses specified by as follows.
•For FX
3U and FX3UC PLCs :16-bit instruction→1 to 32,767PLS
32-bit instruction→1 to 2,147,483,647PLS
•For FX
3S, FX3G and FX3GC PLCs :16-bit instruction→1 to 32,767PLS
32-bit instruction→1 to 2,147,483,647PLS
•For FX
2N and FX2NC PLCs :16-bit instruction→110 to 32,767PLS
32-bit instruction→110 to 2,147,483,647PLS
When setting a value less than "110", the operation is as follows.
PLC version V3.00 or before : The pulses are not generated normally.
PLC version V3.00 or later : One tenth of the maximum frequency is generated.
If the maximum frequency is 100 Hz or less, "10 Hz" is generated.
•For FX
1S, FX1N and FX1NC PLCs : 16-bit instruction→110 to 32,767(PLS)
32-bit instruction→110 to 999,999(PLS)
When setting a value less than "110", the pulses are not generated normally.
3. Acceleration/deceleration time
Set the acceleration/deceleration time specified by as follows.
For FX
3S, FX3G, FX3GC, FX3U and FX3UC PLCs: 50 to 5000 (ms)
For FX
2N and FX2NC PLCs: 5000 (ms) or less
Follow, however, the conditions a) through d).
a) Make the acceleration/deceleration time be 10 times or more the PLC's maximum scan time (value of
D8012 or greater). If set to less than 10 times, the acceleration/deceleration timing becomes instable.
b) The following equation defines the allowable minimum that can be set as the acceleration/
deceleration time.
If setting a value less than the equation indicates, the error in the acceleration time becomes large. If
set to less than "90000/ , operation takes place while rounding it up to "90000/ ".
c) The following equation defines the allowable maximum that can be set as the acceleration/
deceleration time.
d) The number of speed changes (steps) for the acceleration/deceleration is fixed to "10 times" as shown
in the previous page.
If unable to set the PLC to these conditions, lower the maximum frequency specified by .
•For FX1S, FX1N and FX1NC PLCs: 50 to 5000(ms)
4. Pulse output
• Only a transistor output on the main unit or Y000 or Y001 on a special high speed output adapter
*1
can be
specified in .
*1. Special high speed output adapters can be connected only to the FX
3U PLC.
When using the PLSR instruction with a relay output type or triac output type FX
3U PLC, a special
highspeed output adapter is required.
• 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.
