Error message Possible cause of error
Additional information and descriptions in
the manual
8BD0 Excessive The following error of a moving axis is
greater than the value given in machine
servo lag in <axis>
parameter MP1720.x (in lag mode) or MP
1420.x (feedforward mode).
The acceleration entered is too large.
The motor is not moving even though drive-
on was given.
Overloaded driver
Insufficient lubrication
Mechanical stiffness
Machine vibration
Hardware error in the control loop
For analog axes: servo defective
8BE0 Encoder Incorrect nominal distance between two
reference marks
defective <axis>
8BF0 Input Noise on speed encoder signals
frequency from
speed encoder
<axis>
8C00 Input Noise on position encoder signals
frequency from
position encoder
<axis>
8C10 <axis> No encoder signal available
motor encoder
Interruption in motor encoder cable
defective
Signal amplitude of motor encoder is
missing or too small.
A080 CC%d The automatic SRG, SBH, and SH operating
states of the MC and CC are compared
operating state
cyclically. If the values remain unequal for
not equal MC
longer than 500 ms, a Stop 1 is released.

Measures for error diagnosis and/or
corrective action
Additional information and descriptions in
the manual
Reduce the feed rate and increase the
spindle speed.
Remove potential sources of vibration.
The motor current must not be limited
during acceleration.
Check the lubrication.
Remove mechanical stiffness.
Analog axes: Check the servo.
Check the acceleration.
See "Sequence for Finding Errors in the
Control Loop" on page 6 – 62.
Carry out offset adjustment (See "Adjusting
the electrical offset (drift adjustment)" on
page 20 – 349).
Carry out speed adjustment (See "Speed
adjustment at the servo amplifier
(tachometer adjustment)" on page 20 –
352).
Check the entry in the motor table and
MP2206.x.
Check the entry in MP334.x.
Check if the reference signal is disturbed.
See "Encoder Interface" on page 18 – 277.
Check the encoder signals.
Check the shielding.
See "Further Examination of Position and
Speed Encoders" on page 18 – 308.
Check the encoder signals.
Check the shielding.
See "Further Examination of Position and
Speed Encoders" on page 18 – 308.
Check connection of motor encoder.
Check the motor encoder.
Check the amplitude of the encoder signal.
See "Speed Encoders" on page 18 – 293.
See Service Manual Inverter Systems and
Motors.
Press CE to acknowledge the error
message.
Switch on the machine.
Check the software version.
