Execution of Origin Setting (Fn020)
When using an absolute linear scale model ST78
A
manufactured by Mitutoyo
Corporation, execute the origin setting.
The origin setting can be executed by using either the digital operator or panel opera-
tor.
Using the Panel Operator
CAUTION
• Be sure to set the linear servomotor to the servo OFF state before executing
the origin setting function.
• Make sure that the parameter Fn010 (Write Prohibited Setting) is not set to
prohibit writing.
• After execution of the origin setting, the servo ready (/S-RDY) signal will
become inactive and the servo will be unable to draw power since the system
position data has been changed. Always turn the power supply OFF and then
ON again after execution of origin setting.
• After execution of the origin setting, the motor phase data in the SERVOPACK
will be lost. Execute the polarity detection (Fn080) and save the motor phase
data in the SERVOPACK.
• Origin setting using the utility function is required only for the initial setup.
If the position data is carelessly changed, the origin of the linear scale will be changed
and the machine may move in unexpected ways, resulting in damage to the product or
injury.
