6.13.7 Alarm Output from the Output Ports for the Position
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 SEN (Absolute Data Request)
turns OFF.
