9.3 Function and Operation
B - 128
The rotation direction ON/OFF status of the specified device is shown in the following table.
During instruction execution, however, do not use the output for other purposes.
5) The interrupt input signal depends on the pulse output of as shown in the following table.
Use an FX
3UC PLC Ver.1.30 or later to use the interrupt input specification function.
Use an FX
3U/FX3UC PLC Ver.2.20 or later to set the user interrupt input command.
*1. Y003 can be specified as the pulse output destination only if two FX3U-2HSY-ADP adapters are connected to
the FX
3U PLC.
Designation of interrupt input using M8336 interrupt input specification function:
1) Turn on the M8336.
2)
Set the interrupt input number (X000 to X007) in D8336, or specify the user interrupt input
command
*1
.
→ For details on the specification method, refer to Subsection 4.3.7 or Subsection 4.5.1.
ON/OFF status of device
specified by
Rotation direction (increase/decrease current value)
ON
If the number of pulses to be output after interruption (specified by ) is set to a positive
number, the operation will be performed in the forward rotation direction.
Forward rotation (Outputting pulses from
will increase the current value.)
OFF
If the number of pulses to be output after interruption (specified by ) is set to a
negative number, the operation will be performed in the reverse rotation direction.
Reverse rotation (Outputting pulses from
will decrease the current value.)
