8BE0 Encoder
defective <axis>
 Incorrect nominal distance between two
reference marks
 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 19 – 277.
8BF0 Input
frequency from
speed encoder
<axis>
 Noise on speed encoder signals  Check the encoder signals.
 Check the shielding.
 See ”Further examination of position and
speed encoders” on page 19 – 314.
8C00 Input
frequency from
position encoder
<axis>
 Noise on position encoder signals  Check the encoder signals.
 Check the shielding.
 See ”Further examination of position and
speed encoders” on page 19 – 314.
8C10 Motor
encoder <axis>
defective
 No encoder signal available
 Interruption in motor encoder cable
 Signal amplitude of motor encoder is missing
or too small.
 Check connection of motor encoder.
 Check the motor encoder.
 Check the amplitude of the encoder signal.
 See ”Speed encoders” on page 19 – 300.
 See Service Manual Inverter Systems and
Motors.
A080 CC%d
operating state
not equal MC
 The automatic SRG, SBH, and SH operating
states of the MC and CC are compared
cyclically. If the values remain unequal for
longer than 500 ms, a Stop 1 is released.
 Press CE to acknowledge the error message.
 Switch on the machine.
 Check the software version.
AC00 CC
amplitude too high
%.2s
 The amplitude of the encoder signal is too high
or the contamination signal active.
 Noise on motor encoder signal
 Short circuit in motor encoder cable.
 Motor encoder signal amplitude too high
 Check connection of motor encoder (ground
connection).
 Check the motor encoder.
 Noise on signal
 Scanning head too close to scale
 For very old encoders: Incandescent lamp too
bright (spiral-wound filament short-circuited)
 Adjust the scanning head.
 See ”Encoder
interface” on page 19 – 277.
AC10 Motor
encoder <axis>
defective
 No encoder signal available
 Interruption in motor encoder cable
 Signal amplitude of motor encoder is missing or
too small.
 Check connection of motor encoder.
 Check the motor encoder.
 Check the amplitude of the encoder signal.
 See ”Encoder interface” on page 19 – 277.
AC20 CC
frequency too
high %.2s
 The maximum input frequency was exceeded
at an encoder input.
 Noise on motor encoder signal
 Check connection of motor encoder (ground
connection).
 Check the motor encoder.
 Check encoder signal input frequency.
 See ”Speed encoders” on page 19 – 300.
