b) In MDI mode, the “Whether it is bus” on the bus configuration interface is set to 1,
“Encoder type” set to 1, and set the machine zero position based upon each axis
manually.
c) Move the cursor to the
, the zero return indicator lights on by pressing the
<Input> twice, and the current position record of the motor’s absolute encoder along
with each axis is regarded as machine zero. Still, the zero indicator lights on after the
system is turn on again. Manually set the negative boundary and positive one based
upon the actual Max. stroke of the machine, so that the current machine absolute
coordinate offsets forward or backward a value; lastly, the bit parameter
No.61#6
is set
to 1, the positive or negative limit is then enabled.
Setting range: -99999.9999~99999.9999, also, the positive/negative boundary of each
axis can be directly set by parameters
P450~P459.
d) Whether configure the grating or not. Set whether separately configure the grating along
with each axis, 0: Without configured grating, 1: With configured grating. Also, it can be
separately set by bit parameters
No: 1#3~1#7.
e) Confirm it by pressing the .
Note 1:
After the machine zero is set, if the system that is altered the zero return direction along with each axis, the
feed axis direction, the servo and system gear ratio will cause zero missing; and it is necessary to set the
machine zero again.
Note 2:
After the machine zero is set again, it will be affected other reference point, for example, the 2
nd
and the
3
rd
reference point should be set again.
For example:
The absolute encoder zero setting can be set the zero position based upon the absolute position
of the motor’s feedback. Set the bit parameters #20.7=1, #20.6=1 and #20.5=1; refer to the Fig.
4-8-2-3.

Note 1:
Never attempt to operation the mechanical zero if the machine tool does not install the zero deceleration switch or
does not set the mechanical zero.
Note 2:
The corresponding axis’s indicator lights up when ends of the mechanical zero return.
Note 3:
The zero return indicator lights off when the corresponding axis does not on the mechanical zero.
Note 4:
Mechanical point (that is the reference position) direction, refer to the machine user manual made by the
