Descriptions of functions
10.4 Communication via PROFIBUS DP
Power electronics faulted
An impermissible operating state of the power electronics was detected (overcurrent,
overtemperature, etc.). Check compliance with the permissible load cycles. Check the
ambient temperatures (fan).
Overtemp. electronic component
The temperature in the component has exceeded the highest permissible limit. Check the
ambient temperature / control cabinet ventilation.
Ground fault / inter-phase short-circuit detected
A ground fault / inter-phase short-circuit was detected in the power cables or in the motor
windings. Check the power cables (connection). Check the motor.
Motor overload
The motor was operated outside the permissible limits (temperature, current, torque...).
Check the load cycles and set limits. Check the ambient temperature / motor cooling.
Communication to the controller faulted
The communication to the higher-level controller (internal coupling, PROFIBUS, PROFINET,
etc.) is faulted or interrupted. Check the state of the higher-level controller. Check the
communication connection/wiring. Check the bus configuration/cycles.
Actual position/speed value error
An illegal signal state was detected while evaluating the encoder signals (track signals, zero
marks, absolute values, etc.). Check the encoder / state of the encoder signals. Observe the
maximum permissible frequencies.
Internal communication faulted
The internal communication between the SINAMICS components is faulted or interrupted.
Check the DRIVE-CLiQ wiring. Ensure an EMC-compliant installation. Observe the
maximum permissible quantity structures / cycles.
External signal state error
A measured value / signal state read-in via the input area (digital/analog/temperature) has
assumed an impermissible value/state. Identify and check the relevant signal. Check the set
thresholds.
Application / function faulted
The application / technological function has exceeded a (set) limit (position, velocity, torque,
etc.). Identify and check the relevant limit. Check the setpoint specification of the higher-level
controller.
Error in the parameterization / commissioning
An error was identified in the parameterization or in a commissioning procedure, or the
parameterization does not match the actual device configuration. Determine the exact cause
of the error with the commissioning tool, adapt the parameterization or device configuration.
