7.9 Setting of the absolute encoder (Fn008)
The absolute encoder must be set (initialized):
●
When the machine is initially started.
●
When the "Encoder backup alarm (ER.810)" occurs.
●
When the serial data of the absolute encoder's rotation is to be initialized.
The basic setup (initialization) steps are shown below.
Steps

Operations
1
Press MODE/SET to select the auxiliary function. Adjust
by pressing UP or DOWN until Fn000 is displayed.
2
Adjust by pressing UP or DOWN until Fn008 is displayed.
3
Press the DATA/SHIFT key for about 1 second, then
PGCL1 is displayed.
4
Press and hold the UP button until "PGCL2" is displayed.
5
(blinking)
Press MODE/SET to start setting (initializing) the absolute
encoder. After setting is complete, donE flashes for about
1 second.
6
-
After displaying donE, the display of "PGCL2" is returned.
7
Pressing the DATA/SHIFT key returns the display to
Fn008.
CAUTION
●
After setting the absolute value encoder, the rotation data is the value in the range of - 2
revolutions to + 2 revolutions. Due to mechanical system, the reference position of the upper
device will change. Please determine the reference position of the upper device according to the
set position.
●
If the machine is operated without positioning the upper device, unexpected mechanical
action may occur, resulting in personal accidents, Or mechanical damage, please operate the
machine carefully.
●
Parameter prohibition function (fn010) cannot be set to "write prohibition";
●
Please perform basic setting (initialization) in servo off state.
●
"Encoder backup alarm (ER. 810)" cannot be input through the alarm reset (/ alm-rst) of the
servo unit. For signal contact, be sure to set (initialize) through fn008.
●
