Note: 1. The motor rotates during execution of Auto-Tuning of PG-E3 encoder characteristics. Before starting, refer to the drive technical
manual.
2. Auto-Tuning of PG-E3 encoder characteristics adjusts the unique characteristics of the ERN1387 encoder connected to the drive by
using a PG-E3 option card. This type of tuning should be performed when setting up the drive or after replacing the encoder or drive.
The signal lines between the PG-E3 option card and the ERN1387 encoder must be connected between the R+ and R- terminals while
this type of tuning is performed.
3. The setting values of parameters F1-66 to F1-81 are reset to factory default values when A1-03 is set to 2220. The setting values of
parameters F1-66 to F1-81 are modified at completion of Auto-Tuning of PG-E3 encoder characteristics.
■ Auto-Tuning Interruption and Fault Codes
If tuning results are abnormal or the STOP key is pressed before completion, Auto-Tuning will be interrupted and a fault
code will appear on the digital operator.
