Output frequencies
Constant for SPED:
10 to 99,990 Hz
Word for SPED: 6 Hz
to 200 kHz
6 Hz to 200 kHz 6 Hz to 200 kHz
Although the above ranges can be set for the instructions, the output frequency range is
ultimately controlled by the clock frequency. The output frequencies are obtained by dividing the
clock pulse with an integer dividing ratio, meaning the actual output frequency can be different
from the set frequency.
The settings in the User Setup Area are as follows (DM 6613 and DM 6614, bits 08 to 15):
00 Hex: 25 MHz
Pulse output frequency range: 400 Hz to 200 kHz
01 Hex: 6.25 MHz (25/4) Pulse output frequency range: 100 Hz to 100 kHz
02 Hex: 1.5625 MHz (25/16) Pulse output frequency range: 25 Hz to 50 kHz
03 Hex: 390.625 kHz (25/64) Pulse output frequency range: 6 Hz to 20 kHz
Frequency
acceleration/
deceleration rate --- 1 Hz to 2 kHz every 2 ms
Duty ratio 50%
Pulse output modes One of the following can be set for each port in the User Setup Area.
1) Relative pulse output (No. of output pulses = pulse output value)
2) Linear-mode absolute pulse output (No. of output pulses = |PV of pulse output – target pulse
amount)|
3) Ring-mode absolute pulse output (As above. If the ring set value is exceeded, the count
value returns to 0000 0000 Hex.) (Ring set value is set in Unit Setup Area.)
4) Electronic cam mode (output with absolute position specification) The direction is
automatically determined from the relation between the PV and target position (PV < Target =
CW, PV> Target = CCW) (No. of output pulses = |PV of pulse output – target pulse amount)|
5) One-shot pulse output (Pulse turned ON for specified time between 0.01 and 9,999 ms via
STIM instruction)
6) Pulse counter timer (High-precision timer created using the one-shot pulse output function.)
Pulses are not output externally.
Number of pulse
outputs 1) Relative pulse output: 0000 0000 to FFFF FFFF Hex
2) Linear-mode absolute pulse output: 8000 0000 to 7FFF FFFF Hex
3) Ring-mode absolute pulse output: 0000 0000 to Ring set value Hex
4) Electronic cam mode (output with absolute position specification):
8000 0000 to 7FFF FFFF Hex
The number of pulses is not set for a one-shot pulse output or pulse counter timer.
Storage location for
PV of pulse output The PV for the above output pulses 1 to 4 are stored as follows:
Port 1: AR 15 (upper bytes), AR 14 (lower bytes)
Port 2: AR 17 (upper bytes), AR 16 (lower bytes)
Target value interrupts or bit pattern outputs for range comparisons can be performed for the
PV. The contents of the above words is updated during the I/O refresh period.
