Origin Search Flag: HOME_R (Byte 2, Bit 7)
The HOME_R bit reflects the status of the Origin Search Command. The host device
can confirm by the change of status of this flag that the DeviceNet Unit has correctly
received a change in the Origin Search Command.
This flag is set to 1 even if the origin search cannot be executed because of a Servo OFF
status, for example. The user must monitor for alarms during origin search. The host
device can confirm that the origin search is being executed by checking that the
Progressing Flag is set to 1.
Relative Specification Flag: INC_R (Byte 3, Bit 0)
The INC_R bit reflects the status of the Relative Specification. The host device can
confirm by the change of status of this flag that the DeviceNet Unit has correctly
received a change in the relative specification.
Movement Direction Flag: DIR_R (Byte 3, Bit 1)
The DIR_R bit reflects the status of the Movement Direction Command. The host
device can confirm by the change of status of this flag that the DeviceNet Unit has
correctly received a change in the Movement Direction.
Origin Flag: HOME_P (Byte 3, Bit 3)
The HOME_P bit is set to 1 when the Servomotor is within the origin range. The origin
range is set in Pn806 (Zero Position Output Width
When an incremental position detection system is used, this flag cannot be set to 1 for
the period from when power is turned ON to the W-series Servo Driver until the initial
origin search has been completed.
Near Signal Flag: NEAR (Byte 3, Bit 4)
The NEAR bit is set to 1 when the present position is within the In-position range. When
the present position is outside the In-position range, the flag is set to 0. The In-position
range is set in Pn852 (Positioning Near Range
In-position Flag: INPOS (Byte 3, Bit 5)
The INPOS bit is set to 1 when the present position is within the positioning completed
range of the target position. The flag is set to 0 when the present position is outside the
positioning completed range. The In-position range is set in Pn850 (Positioning
Completion Range).
