The figure below shows the relationship between the parameters and the special data regis-
ters while the machine zero return operation is performed.
Special auxiliary relay M9057 (x axis) and M9089 (y axis) operate completing the machine
zero return.
Again, if the machine zero return command is done, each special auxiliary relay becomes turn-
ing off, and becomes on again because of the zero return completion.
The relays M9057 and M9089 remain actuated when the mode is changed over from MANU to
AUTO after the machine zero return operation is performed in the MANU mode.

Writes parameters
Does not require
writing especially.
Transmits when the power is turned
ON or when the mode is changed
over from MANU to AUTO.
This indicates the absolute address
from the machine zero point, and
functions as the address for
electrical zero return performed by
the DRVR instruction.
Writes when the machine zero
return operation is completed.
Transmits when the power is turned
ON or when the mode is changed
over from MANU to AUTO.

(Unit used)
*1 Transmitted also to D9075 and D9074 for pulse conversion.
The pulse conversion value is written in the current value
(pulse conversion value) (x axis:D9075, D9074, and y
axis:D9095 and D9094).
