YASKAWA VS-616PS5 Series Quick Start Manual page 44

When T1-03 is set to "01", the most common fault seen will be Er-18. When Er-18 is displayed, shut off power and
check the connections to the motor and to the hall sensor and/or encoder.
If two or more attempts to orient the encoder fail (i.e., "End" is not displayed at the end of the sequence), you will
need to change parameter F1-05 and re-initiate the auto tuning process as described above. It may be necessary
to change A1-03 to "0003" (Basic Parameter Group) to access this parameter (depends on Software version).
