AMM8A SSI & BiSS C-mode
6.5.5 Aligning the encoder
As soon as the parameters control operation is carried out positively, the
program enters automatically the encoder mechanical alignment operation. A
blue arrow appears next to the
Mechanical alignment
item. A graphical
picture of the encoder and all the tools useful to the operator for executing the
mechanical alignment of the device will appear on the right of the page.
If the encoder is not aligned properly over the code disk, the position reference
indicator in the vertical bar with numeric scale will be placed in the upper or
lower red sections; furthermore a double headed yellow arrow will appear on
the encoder picture. The deviation from the perfect position will be shown
under the picture.
Mechanically adjust the position of the encoder unit until it is well aligned over
the code disk (
Step 7
of the mounting instructions); the position reference
indicator in the vertical bar must be well centred in the middle green section.
The
message will appear under the encoder picture.
Tighten the three bolts down to firmly fix the encoder unit, torque to 1.3 Nm
max. Hold the encoder unit down and avoid any movements while tightening.
When the encoder unit is fixed press the
DONE
button to complete the
mechanical alignment operation (
Step 8
of the mounting instructions).
If everything is ok, a green tick (
) will appear next to the
Mechanical
alignment
item and the program will start the next step automatically.
On the contrary, if an error occurs during the mechanical alignment operation, a
red
will appear next to the
Mechanical alignment
item. You will need to
repeat the operation and check, for instance, if the disk is dirty.
