Event name Excessive Hybrid Following Error Event code 383F0000 hex
Meaning During fully-closed control, the difference between the load position from the external encoder and the Servomotor
position from the encoder was larger than the number of pulses set as the Hybrid Following Error Counter Overflow
Level (3328 hex).

Cause and
correction
Assumed cause Remedy Prevention
Connections are not correct. Correct any mistakes in the
connections between the Servomotor
and load or between the external
encoder and Servo Drive.
Make sure that the connections
between the Servomotor and load or
between the external encoder and
Servo Drive are correct.
The settings are not correct. If the change in the Servomotor
position (encoder feedback value)
and the change in the load position
(external encoder feedback value) do
not have matching signs when the
load is moved, correct the settings of
the External Feedback Pulse Dividing
Numerator and Denominator (3324
hex and 3325 hex), and the External
Feedback Pulse Direction Switching
(3326 hex).
Set the External Feedback Pulse
Dividing Numerator and Denominator
as well as the External Feedback
Pulse Direction Switching so that the
change in the Servomotor position
and change in the load position result
in the same sign when the load is
moved.
