Serial Converter Unit
The Serial Converter Unit converts the signal from the linear encoder into
a form that can be read by the SERVOPACK.
Scale Pitch
A linear encoder has a scale for measuring lengths (positions). The
length of one division on this scale is the scale pitch.

You will not be able to control the Linear Servomotor if Pn282 is not set correctly. Check
the above table and always set the correct value before you operate the Linear Servo-
motor.

The first time you supply power to the SERVOPACK, the panel display on the front of the
Servomotor will display an A.080 alarm (Linear Encoder Pitch Setting Error). The A.080
alarm is displayed because the setting of Pn282 has not been changed. The A.080 alarm
will be cleared when you change the setting of Pn282 and then turn the power supply
OFF and ON again.
Linear Encoder Pitch
If you do not use a Serial Converter Unit, the linear encoder pitch is auto-
matically set. It is not necessary to set Pn282. You can use the SigmaWin
+ to check the linear encoder pitch that was automatically set. Refer to
the following section for details.
