Arith. & Logic
Operation
*1. The setting range is from 10 to 100,000 Hz in FX3G/FX3GC/FX3U/FX3UC PLCs.
The setting range is from 10 to 200,000 Hz in FX
3U PLC when the pulse output destination is the high-speed
output special adapter.
*2. The creep speed should satisfy the relationship "Bias speed ≤ Creep speed ≤ Maximum speed".
*3. An interrupt input set here cannot be used jointly with a high-speed counter, input interrupt, pulse catch input,
input in SPD (FNC 67) instruction, or interrupt input in DVIT (FNC151) instruction.
*4. This area can be set only in FX
3U/FX3UC PLCs.
*5. Y002 is not set in FX
3G PLC (14-point and 24-point type) and FX3GC PLC.
*6. Note that this item can only be set if two high-speed output special adapters are connected to the FX
3U PLC.
Set item Contents of setting Set range
Bias Speed [Hz]
Set the bias speed for each set of output pulses.
Initial value: 0
1/10 or less of the
maximum speed
Max. Speed [Hz]
Set the maximum speed for each set of output pulses.
Initial value: 100,000
*1
Creep Speed [Hz]
Set the creep speed in DSZR (FNC150) instruction for each set of output pulses.
Initial value: 1000
10 to 32767
*2
Zero Return Speed [Hz]
Set the zero point return speed in DSZR (FNC150) instruction for each set of
output pulses.
Initial value: 50000
*1
Acceleration Time [ms]
Set the acceleration time for each set of output pulses.
Initial value: 100
50 to 5000
Deceleration Time [ms]
Set the deceleration time for each set of output pulses.
Initial value: 100
50 to 5000
Interruption Input of DVIT
Instruction
*4
Set the interrupt input
*3
for DVIT (FNC151) instruction for each set of output
pulses. Specify a user interrupt command device (M) for a pulse output
destination device not used in DVIT instruction.
Initial setting: Setting range:
Pulse output destination Y000: X000 X000 to X007, M8460
Pulse output destination Y001: X001 X000 to X007, M8461
Pulse output destination Y002: X002 X000 to X007, M8462
Pulse output destination Y003
*6
: X003 X000 to X007, M8463
