Absolute Encoder Origin Setting (Fnb09) - YASKAWA S-V Series User Manual

8.2.8 Absolute Encoder Origin Setting (FnB09)

This utility function replaces the current position with a specified position. Also updates PnB25 with the abso-
lute position offset value to achieve the position specified by this utility function.
• This function replaces the coordinates of the reference position and is therefore very dangerous. After exe-
cuting this function, check that the new coordinates match the reference position before starting operation.
• If the settings for any of parameters Pn20E to Pn210, Pn205, or PnB20 to PnB25 have been changed,
turn the control power supply off and back on to bring the settings into effect before executing operation.
• The absolute position offset value is saved in parameter PnB25, so do not rewrite this value.
(1) Preparation
The following conditions must be met to perform the absolute encoder origin setting.
• The write-prohibited setting (Fn010) must not be set to write-protect parameters.
• Position references must not being distributed.
• The absolute position offset value must not be outside the range for PnB25.
• The absolute encoder must be connected and the setting for Pn002.2 must be 0.
