Cause: A changeover of units was initiated. This resulted in a violation of a parameter limit
Possible causes f
or the violation of a parameter limit:
- When rounding o󹪜 a parameter corresponding to its decimal places, the steady-state minimum limit or maximum limit
was violated.
- Inaccuracies for the data type "FloatingPoint".
In these cases, when the minimum limit is violated then the parameter value is rounded up and when the maximum limited
is violated the parameter value is rounded down.
Fault value (r0949, interpret decimal).
Remedy: Check the adapted parameter values and if required correct.
A07089 Unit switchover: Function activation is blocked because the units have been switched over
Message class: Error in the parameterization / con󹪝guration / commissioning procedure (18)
Message value: -
Component: None
Response: NONE
Acknowledgment: NONE
Cause: An attempt was made to activate a function. This is not permissible if the units have already been changed over.
Remedy: Restore units that have been changed over to the factory setting.
F07090 Drive: Upper torque limit less than the lower torque limit
Message class: Error in the parameterization / con󹪝guration / commissioning pr
ocedure (18)
Message value: -
Component: None
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: The upper torque limit is lower than the lower torque limit.
Remedy: When setting the torque limits via telegram 750, the positive torque limit must be >= the negative torque.
A07091 Drive: determined current controller dynamic response invalid
Message class: Error in the parameterization / con󹪝guration / commissioning procedure (18)
Message value: %1
Component: Control Unit (CU)
Response: NONE
Acknowledgment: NONE
Cause: When One Button Tuning is activated (p5300 = 1), the current controller is measured after the pulses have been enabled.
Ev
aluation has indicated t
hat the current control loop was not appropriately set.
Possible causes:
- Incorrectly set current controller.
- PRBS amplitude set too high (p5296).
Alarm value (r2124, interpret hexadecimal):
1: Dynamic response too low.
2: Current controller unstable.
Note:
PRBS: Pseudo Random Binary Signal (binary noise)
Remedy: - The measurement can be repeated with a smaller excitation amplitude (p5296).
A07092 Drive: moment of inertia estimator still not ready
Message class: Error in the parameterization / con󹪝guration / commissioning pr
ocedure (18)
Message value: %1
Component: Control Unit (CU)
