TIM-PN
SETTINGS
If, for instance, the torque value is incorrect (e.g. actual value > 120% of the rated value or
transmission error between rotor and stator), then the output will conform to what you
have set under error specification. If you selected Overflow, the torque value will change
to 7FFFFFFFh in the case of an error.
For how long the error should be signaled on the PROFINET interface can be set manu­
ally, or automatically determined by the system.
If you select automatic, the error duration for dynamic errors will be specified subject to
the set filter. Static errors are displayed until they are rectified.

Table of errors in torque
CRC5 failure in
sequence
[dynamic]
During transmission from the torque transducer to TIM-PN, a
CRC error is detected in more than 5 values in direct sequence
(otherwise the preceding, old, correct value is taken)
Measured value not
sent (stator has
detected failures or
transmission is
defective)
[dynamic]
If a measured value is not sent at all, the failure state must be
assumed immediately. If the stator can be accessed, the
device failures are also updated.
Linearization failure
[static]
Linearization is active, but the rotor serial number is different
to that in the TIM-PN device.
Measured value
overflow or underflow
[dynamic]
The limit for T40 is +/- 120% of the nominal (rated) torque.
