FX Series Positioning Controllers
The figure below shows the relationship between the parameters and the special data regis-
ters while the machine zero return operation is performed.
Valid only for the X
axis in the FX
PARA 16 : Machine zero point
address X axis, Y axis
Transmits when the power is turned
ON or when the mode is changed
over from MANU to AUTO.
Special data registers
X axis : D9233, D9232
Y axis : D9433, D9432
Writes when the machine zero
return operation is completed.
Special data registers *1
X axis : D9005, D9004
Y axis : D9015, D9014
Forward
rotation pulse
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.

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

PARA 24 : Electrical zero point
Transmits when the power is turned
ON or when the mode is changed
over from MANU to AUTO.
Special data registers
X axis : D9249, D9248
Y axis : D9449, D9448
This indicates the absolute address
from the machine zero point, and
cod29
functions as the address for
electrical zero return performed by
SETR
the DRVR instruction.
