Number Cause Check and action
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
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 (I298)
16: X4 busy Defective encoder cable Check the cable and replace it if necessary
Inconsistent
parameterization
Compare the connected encoder to the
parameterized encoder and correct it if
necessary (H00)
Incompatible encoder Compare the specification of the encoder
with the corresponding specifications from
STOBER and replace the encoder or motor
if necessary
