FX Series Programmable Controlers Applied Instructions 5

5.6.10 PLSR (FNC 59)
Operation:
A specified quantity of pulses S
2 is output through
device D. The output frequency is first ramped up in
10 steps to the maximum frequency S
1 in
acceleration time S
3 ms, then ramped down to stop
also in S
3 ms. This instruction is used to generate
simple acc/dec curves where the quantity of outputs
is of primary concern.
Points to Note:
a) FX
2N/FX2NC users may use frequencies of 10 to 20,000Hz. FX1S/FX1N users may use
frequencies of 10 to 100,000Hz. The frequency should be set to a multiple of 10. If not it will
be rounded up to the next multiple of 10.
The acceleration and deceleration steps are set to 1/10 of the maximum frequency. Take
this in to consideration to prevent slipping, when using stepping motors.
b) FX
2N and FX2NC units with CPU of less than V3.00 and all FX1S,FX1N units,
maximum number of pulses: 16 bit operation: 110 to 32,767 pulses,
32 bit operation: 110 to 2,147,483,647 pulses.
Correct pulse output can not be guaranteed for a setting of 110 or less.
FX
2N and FX2NC units with CPU of V3.00 or greater,
maximum number of pulses: 16 bit operation: 0 to 32,767 pulses,
32 bit operation: 0 to 2,147,483,647 pulses.
A setting of 110 pulses or less, or a frequency of [S
1
]/10 will result in no acceleration.
