Homing

Homing is used to define the machine origin when the power supply is turned ON to equipment
that uses an incremental encoder. Turn OFF (mode 1) the /MODE 0/1 (Mode Selection Input)
signal to enable performing homing. In mode 1, CN11-5 will be the /HOME (Homing Input) sig-
nal.

13.2.1 I/O Signals Related to Homing

/HOME
/DEC
Output Signals Related to Homing
Output Signal
/INPOSITION
Note

 If you are using an incremental encoder, always perform homing before you start program
table operation. If you perform program table operation without performing homing, posi-
tions cannot be managed so correct positioning may not be possible.
Unexpected machine operation, failure, or personal injury may occur.
ON: Mode 0 (program table operation)
OFF: Mode 1 (jog speed table operation or homing)
The /HOME signal is turned ON to start homing.
The /DEC signal is used to change the homing speed, but its function
depends on the setting of the homing method (PnB31).
This signal turns ON when the current position is within the positioning
completed width of the target position (final travel distance). It also turns
ON when the Servomotor stops after positioning is canceled, even if the
target position was not reached.
Homing is not performed for an absolute encoder.
Therefore, error E61E (Encoder Mismatch Error) will occur if the /HOME signal turns ON.
