Cause
Position error pulses exceeded the setting of
the Following error window (6065 hex).
• Motor operation does not follow the
command.
• The value of the Following error window
(6065 hex) is small.
The difference (speed deviation) between
Motor Velocity Demand Value After Filtering
and actual speed has exceeded the set
value of the Excessive Speed Deviation
*3
Setting (3602 hex).
The motor speed exceeded the value set in
Overspeed Level (3910 hex).
The motor speed exceeded the value set for
the Overspeed Detection Level Setting at
Immediate Stop (3615 hex).
The position command variation after the
electronic gear is higher than the specified
value.
During position command processing, an
error such as an "over the calculation range"
error occurred.
An attempt was made to establish EtherCAT
communications (change from Init to Pre-
Operational state) or to turn ON the servo
from the controller (enable operation) while
executing an FFT that operates with the
Servo Drive alone or a trial run.
A Config operation was performed was
cleared for the absolute encoder during
EtherCAT communications.

Measures
• Check to see if the motor operates
according to the position command pulse.
Check on the force monitor to see if the
output force is saturated. Adjust the gain.
Maximize the Force Limit setting being
used. Wire the external encoder as shown
in the wiring diagram. Lengthen the
acceleration and deceleration times.
Reduce the load and the speed.
• Increase the set value of object 6065 hex.
• Increase the set value of the Excessive
Speed Deviation Setting (3602 hex) object.
• Lengthen the acceleration time of the
Motor Velocity Demand Value After
Filtering. Alternatively, improve the
tracking (following) performance by
adjusting the gain.
• Disable the Excessive Speed Deviation
Setting (3602 hex).
• Do not give excessive speed commands.
• Check the input frequency, dividing ratio,
and multiplication ratio of the position
command.
• If overshooting occurred due to faulty gain
adjustment, adjust the gain.
• Wire the external encoder as shown in the
wiring diagram.
• Check to see if the position command
variation is large.
• Check the electronic gear ratio.
• Check to see if the backlash compensation
amount is too large.
Check to see if the electronic gear ratio, and
the acceleration and deceleration rates meet
the restrictions.
Check to see if EtherCAT communications is
established or the servo is turned ON
(enable operation) while an FFT or a trial run
was being conducted.
Check to see if Config operation was
performed was cleared for the absolute
encoder during EtherCAT communications.
