(3) Machine analyzer function

14.3.7 Absolute position detection system

When the linear servo motor is used with the absolute position detection system, an absolute position linear
encoder is required. The linear encoder backs up the absolute position data. Therefore, the encoder battery
need not be installed to the servo amplifier. Additionally, [AL. 25 Absolute position erased], [AL. 92 Battery
cable disconnection warning], [AL. 9F Battery warning], and [AL. E3 Absolute position counter warning] are
not provided for the linear servo motor.
POINT
Make sure to perform the machine analyzer function after the magnetic pole
detection. If the magnetic pole detection is not performed, the machine analyze
function may not operate properly.
The stop position at the completion of the machine analyzer function can be any
position.
