Descriptions of functions
10.5 Communication via PROFINET IO
Messages
The following PROFIdrive error texts are displayed during forwarding via the PROFINET
diagnostics channel:
Hardware/software fault
A hardware or software malfunction was detected. Carry out a POWER ON for the relevant
component. If it occurs again, contact the hotline.
Line supply fault
A line supply fault has occurred (phase failure, voltage level, etc.). Check the line supply and
fuses. Check the supply voltage. Check the wiring.
Supply voltage fault
An electronic power supply fault (48 V, 24 V, 5 V, etc.) was detected. Check the wiring.
Check the voltage level.
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).
Overtemperature of an 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, etc.).
Check the load cycles and set limits. Check the ambient temperature / motor cooling.
Communication to the higher-level 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 incorrect or not available
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 (DRIVE-CLiQ) 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.
