Data from the Absolute Linear Encoder
Any alarm detected by the SERVOPACK is transmitted as the upper 16-bit data (with sign) to the host
controller with the PAO (Encoder Divided Pulse Output) signal when the SENS_ON (Turn ON Sensor)
command turns OFF.

If you are using a Linear Servomotor, you do not need to reset the absolute linear encoder to
define the origin. (Some absolute linear encoders also allow you to set any position as the origin.)
