13 High Speed Processing – FNC 50 to FNC 59
13.10 FNC 59 – PLSR / Acceleration/Deceleration Setup
2. 32-bit operation (DPLSR)
Pulses are output from the output (Y) by the specified number [ +1, ] with acceleration/
deceleration to the maximum frequency [ +1, ] for the time [ +1, ](ms).
[ +1, ]: Maximum frequency (Hz)
- When special high speed output adapters are used
Allowable setting range: 10 to 200,000 (Hz)
- When the FX
3G/FX3U/FX3UC PLC main unit is used
Allowable setting range: 1 to 100,000 (Hz)
[ +1, ]: Total number of output pulses (PLS)
Allowable setting range
FX
3G : 110 to 2,147,483,647 (PLS)
FX
3U/FX3UC : 1 to 2,147,483,647 (PLS)
[ +1, ]: Acceleration/deceleration time (ms)
Allowable setting range: 50 to 5000 (ms)
: Pulse output number
Allowable setting range: Y000, Y001
3. Pulse output specifications
• Simple positioning (with the acceleration/deceleration function)
The operation pattern is as shown below:
• Output processing
The pulse output is controlled by the dedicated hardware regardless of the operation cycle.
• Data change while the instruction is executed
Even if operands are overwritten while the instruction is executed, such changes are not reflected
immediately. The changes become valid the next time the instruction is driven.
