Encoder data recovery
error protection
Initialization of internal position information was unsuc-
cessful under semi-closed control in the absolute
mode.
•
Check if the power supply voltage of encoder is
5VDC±5% (4.75 to 5.25V). Take special care
when the encoder cable is long.
•
Separate motor cables from encoder cables if they
are tied together.
•
Connect a shielded wire to FG.

ery error protection
Initialization of internal position information was unsuc-
cessful under full-closed control in the absolute mode.
•
Check if the power supply voltage of encoder is
5VDC±5% (4.75 to 5.25V). Take special care
when the encoder cable is long.
•
Separate motor cables from external scale con-
nection cables if they are tied together.
•
Connect a shielded wire to FG. Refer to the exter-
nal scale connection diagram.
•
Check the parameter set value.
