01
Encoder
Communica-
tions Error
Illegal data was
received from the
encoder the specified
number of times.
This error is detected if
the data error occurs
four times in a row
during communications
with the encoder.
Noise into the encoder
cable
• Separate the motor cable and the
encoder cable if they are bundled
together.
• Connect the shield to FG.
• Check that the motor ground wire
is connected to FG.
Contact failure of the
signal line, and discon-
nection of the encoder
Replace the encoder cable if it is
broken. Firmly connect the encoder
connector to the Servo Drive.
Power supply undervolt-
age to the encoder
Use the recommended encoder
cable.

00
Excessive
Position
Deviation
Error
The position deviation is
greater than or equal to
the value set in the Fol-
lowing error window.
The motor operation
does not follow the com-
mand.
Identify and remove a cause that
limits the motor operation.
During the acceleration/decelera-
tion, the command may not be fol-
lowed depending on operation
patterns. In that case, adjust the
gain, increase the accelera-
tion/deceleration time or the like.
The value of Following
error window is small.
Increase the setting of the Follow-
ing error window to an acceptable
range.
01
Excessive
Speed Devia-
tion Error
The speed deviation is
greater than or equal to
the value set in the
Excessive Velocity
Deviation Detection
Level.
The motor operation
does not follow the com-
mand because a param-
eter value is
inappropriate.
Adjust the gain to improve the fol-
lowing ability. Or, increase the
acceleration/deceleration time for
the internal position command
velocity.
The output axis of motor
is limited on the opera-
tion by external forces.
Take countermeasures so that the
output axis is not limited on the
operation by external forces.
The value of the Exces-
sive Velocity Deviation
Detection Level is inap-
propriate.
Increase the setting of the Exces-
sive Velocity Deviation Detection
Level to an acceptable range. Dis-
able the Excessive Velocity Devia-
tion Detection if it is unnecessary to
monitor the velocity deviation.
26
00
Excessive
Speed Error
The feedback motor
speed is greater than or
equal to the value set in
the Excessive Speed
Detection Level.
The velocity command
value is too large.
Do not give the excessive velocity
command. Check whether the elec-
tronic gear ratio is set correctly.
Overshooting occurred.
If overshooting occurred due to
faulty gain adjustment, adjust the
gain.
The motor is rotated by
external forces.
Check whether the motor is rotated
by external forces.
27
01
Absolute
Value
Cleared
The multi-rotation counter of the absolute encoder
was cleared.
This operation is performed for
safety and is not an error.
Error No.
