Home Positioning Instruction Input
<EtherCAT and EtherNet/IP I/O Signals to be Used>
 Home Positioning Instruction Input (Input signal 1 - bit 7 / input data byte 0 - bit 7)
The built-in absolute type position detector in ABSODEX does not necessarily require home
positioning upon power-on start. If equipment system configuration requires home positioning, it
can be achieved by home positioning instruction input (Input signal 1 - bit 7 / input data byte 0 -
bit 7).
The input is valid in the pulse string input mode (M6), while it is invalid after pulse string input
code G72 is executed in the NC program.
The home positioning operation has the following related parameters.
For details, refer to “5.PARAMETER SETTING.”
PRM3 Home position offset amount
PRM4 Home positioning direction
PRM5 Home positioning speed
PRM6 Home positioning acceleration and deceleration time
PRM7 Home positioning stop
In addition, the communication code S4, and NC code G28 enables the same motions as the
above home positioning instruction inputs.
 Entry of the forced stop input during home positioning or interruption of home positioning due
to an alarm clears the home position offset amount (PRM3) setting.
After invalidating the forced stop input or resetting the alarm, if the start input is entered, as
is, to begin positioning, ABSODEX may not position properly.
Always perform one of the following operations after invalidating the forced stop input or
resetting the alarm: home positioning, execution of NC code G92.1A0, or turning the power
off and back on again.
