1.5.1 Assignment of Input Numbers
Assign the input numbers of the FX3S/FX3G/FX3GC/FX3U/FX3UC PLC as follows:
Application Input number Remarks
Stop command All input points
Connect a line to any input.
If the line-connected input is turned on, turn off the positioning instruction signal must be turned off.
Zero return command
All input points
Connect a line to any input.
If the line-connected input is turned on, the DSZR or ZRN instruction must be turned on.
Near-point signal (DOG)
All input points
Connect a line to the input of the near-point signal (DOG) specified by DSZR or ZRN instruction.
For details on the near-point signal of the DSZR instruction, refer to Section 6.2.
For details on the near-point signal of the ZRN instruction, refer to Section 6.3.
Point:
• To use the ZRN instruction:
If X000 to X007*1 of the main unit are set for the near-point signal (DOG), the PLC interruption function will be used for processing of the near-point signal (DOG).
Zero-phase signal
X000 to X007*1
Connect a line to the input specified for the zero-phase signal (this input is specified by DSZR instruction).
ABS read All input points
Connect a line if it is necessary to use the absolute position detection system.
Connect a line to the input specified by the ABS instruction.
Use 3 consecutive input points for this function.
JOG command All input points
Connect a line to any input.
If the line-connected input is turned on, the DRVI instruction for the jogging motion must be turned on.

Connection Example 1.5 Assignment of Input/Output NumbersInterrupt input X000 to X007
The interrupt input depends on the pulse output destination specified by the DVIT instruction*2 as shown in the following table. If the version number of the PLC is 1.30 or higher, the interrupt input can be specified.
FX3UC PLC Ver. 1.30 or later
If the interrupt input specification function is used, register D8336 (interrupt input specification register) can specify the interrupt input number (X000 - X007) for each pulse output destination.
For details on the interrupt input specification method, refer to Subsection 4.3.7.
FX3U/FX3UC PLC*4 Ver. 2.20 or later
If the interrupt input specification function is used, register D8336 (interrupt input specification register) can specify the interrupt input number (X000 - X007) for each pulse output destination, or the user interrupt input command can be specified.
For details on the user interrupt input command, refer to Subsection 4.3.7.
The user interrupt input command depends on the pulse output destination as shown in the following table.
Forward rotation limit (LSF)
All input points
Connect a line to any input.
If the line-connected input is turned on, the forward limit relay must be turned on.
The forward limit relay depends on the pulse output destination as shown in the following table.
Reverse rota-tion limit (LSR)
All input points
Connect a line to any input.
If the line-connected input is turned on, the reverse limit relay must be turned on.
The reverse limit relay depends on the pulse output destination as shown in the following table:
Application Input number Remarks
