5.5.2 When Using an Absolute Linear Scale
(1) Executing the Utility Function: Polarity Detection (Fn080)
To adjust the polarity of linear servomotor, use the following utility function: Polarity
Detection (Fn080). Because this function is used as part of the initial setup, it is usu-
ally not necessary to execute this function a second time.
The following items must be confirmed before executing the polarity detection.
• The parameter Fn010 (Writing Prohibited Setting) is not set to prohibit writing.
• Linear servomotor is turned OFF.
The polarity detection can be executed by using either the digital operator or panel
operator.
CAUTION
• If the SERVOPACK, the absolute linear scale, or the linear servomotor is
replaced, the polarity detection function must be executed again.
Failure to observe this caution may result in the linear servomotor moving in an
unpredictable manner.
