16.26 56:Overspeed
Triggering Level Response Counter
The measured velocity I88 is greater than I10 x
1.111.
From firmware 6.0-B: If the motor and position
encoder are two different encoders, I88 and E91 x
I240[1] are checked.
Fault The power board is switched off and the drive becomes
torque-free/force-free unless emergency braking U30
(A29) is parameterized. If the air override is inactive, a
possibly existing brake will be controlled to close.

Possible cause Test Measure Confirmable
Incorrect parameterization of the
encoder
Check the parameterization of the encoder,
e.g. the line number of the incremental
encoders.
If necessary, correct the parameters Yes
Following error too large Use a Scope trace to check whether the
measured velocity is greater than I10 at the
time of the error.
Correct the parameters (ramps, torque
limits, etc.).
Motor overshoots Use a Scope recording to check the value in
E16 is greater than E06 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
from zero is displayed in E91 during a motor
standstill.
The motor must be sent in for repair. Please
contact our Service department.
