(1) Use zeroing at power on and other times where confirmation that axes are at
the machine home position is required.
(2) The following three methods of zeroing are available:
• Proximity dog method
• Count method
• Data set method..........................(Recommended for an absolute-position
(3) To carry out zeroing, the zeroing data must be set for each axis.
The zeroing data is the data required to carry out zeroing.
Set the zeroing data from a peripheral device.

Value
• Sets the direction for zeroing.
0
• Sets the zeroing method.
• The proximity dog method or
count method is recom-
mended for a servo amplifier
0
which does not support ab-
solute data, and the data set
method is recommended for
a servo amplifier which sup-
ports absolute data.
• Sets the current value of the
home position after zeroing.
• It is recommended that the
PLS
0
home position address is set
at the stroke limit upper limit
or lower limit.
• Sets the speed for zeroing.
PLS/s
1
• Sets the creep speed (low
speed immediately before
PLS/s
1
stopping after deceleration
from zeroing speed) after the
proximity dog.
• Sets the travel value after the
proximity dog for the count
method.
−
PLS
• Set greater than the decelera-
tion distance at the zeroing
speed.
• Sets the parameter block to
1
use for zeroing (see Section
4.4).
