Load is too large. Lighten the load.
Reselect the Servomotor.

Occurs when the
motor or full closed-
loop encoder is ro-
tating.
Pn002.3 (fully-
closed encoder
usage method) is
not set correctly.
Correct the setting of
Pn002.3.

Pn206 (number of
fully-closed encoder
pulses) is not set
correctly.
Correct the setting of
Pn206.
Pn51A (motor-load
deviation over level)
is not set correctly.
Correct the setting of
Pn51A according to the
machinery.
The machinery is
not operating prop-
erly.
Check the machinery.
Slipping is occurring
in the power trans-
mission.
Set Pn51A to 0 so that
A.d1 is not detected.
Fully-closed encod-
er wiring error.
Wire the fully-closed en-
coder correctly.
Fully-closed encod-
er is defective.
Replace the fully-closed
encoder.
