Number Cause Check and action
1: Parameter <-> encoder Inconsistent
parameterization Compare the specification of the
connected encoder to the corresponding
values of the H parameters and correct
them if necessary
2: X4 speed Exceeded encoder
maximum velocity Check the actual velocity during a
movement using the scope image (E15)
and adjust the permitted encoder
maximum velocity if necessary (B297)
Connection error Check the connection and shielding and
correct them if necessary
Dynamic reference values
for the Lean motor Check the dynamics of the application
reference values and reduce them if
necessary
Dynamic control of the Lean
motor Check the control settings; if necessary,
reduce the gain (C31, I20) and increase
the adjustment times (C32)
Toggling the Lean motor
position determination
models Check the switchover filter time constant
and increase it if necessary (B137)
6: X4 EnDat encoder found Inconsistent
parameterization Compare the connected encoder to the
parameterized encoder and correct it if
necessary (H00)
7: X4 channel A/incremental Connection error Check the connection and correct it if
necessary
8: X4 no encoder found Connection error Check the connection and correct it if
necessary; restart the drive controller to
switch the encoder supply back on
Defective encoder cable Check the cable and replace it if
necessary; restart the drive controller to
switch the encoder supply back on
Defective power supply Check the encoder power supply and
correct it if necessary; restart the drive
controller to switch the encoder supply
back on
Inconsistent
parameterization Compare the connected encoder to the
parameterized encoder and correct it if
necessary (H00); restart the drive
controller to switch encoder supply back
on
10: X4 channel A/Clk
–
11: X4 channel B/Dat Defective encoder cable Check the cable and replace it if
necessary
13: X4-EnDat alarm Defective EnDat encoder Replace the motor; fault cannot be
acknowledged
14: X4 EnDat CRC
–
15: X4 double transmission Connection error Check the connection and correct it if
necessary
Electromagnetic interference Take EMC recommendations into
account [
}
109] and, if necessary,
increase the fault tolerance (B298)
