13.3.19 56:Overspeed
Resolution Level Response Fault counter
The measured speed is larger than C01
x 1.1 + 100 rpm.
Malfunction The motor always coasts (from V5.0D) except
when U30 Emergency stop is activated. Any exist-
ing brakes are engaged if they were not released
via F100 independent of the device controller.
Z56
Possible cause Test Measure Acknowledgement
Incorrect parameteriza-
tion of the encoder
Check the parameterization of the
encoder, e.g. the line number of the
incremental encoders.
If necessary, correct the parameters. Switch the device on/off or
programmed acknowledge-
ment
Lag error too large Use a Scope recording to check
whether the value in E07 is larger
than C01 at the time of the error.
Correct the parameters (ramps,
torque limits, etc.).
Motor overshoots Use a Scope recording to check the
value in E91 is larger than E07 at the
time of the error.
Optimize the parameterization of the
speed controller (C31 ,C32).
Incorrect commutation
offset for the encoder of
a servo motor
Perform the B40 phase test action. The B40 phase testaction must be in
accordance with specifications.
Encoder faulty Check whether a speed that clearly
differs to zero is displayed in E91
during a motor standstill.
The motor must be sent in for repair.
