Operation
7.6 Communication via PROFINET IO
SINAMICS DCP
272 Operating Instructions, 09/2019, A5E34382853K
When establishing the communication between SINAMICS and a master/controller, the
activated diagnostics mode of this master/controller is first transferred to the drive. With
activated diagnostics, SINAMICS first transfers all pending messages to the
master/controller.
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 fault
A line supply fault has occurred (phase failure, voltage level...). Check the line supply and
fuses. Check the supply voltage. Check the wiring.
Supply voltage fault
An electronics supply voltage fault (48 V, 24 V, 5 V…) 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.
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.
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.
External measured value / signal state outside of the permissible range
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.
Fault in the parameterization/configuration/commissioning procedure
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.
General drive fault
Group fault, determine the exact cause of the fault with the commissioning tool.
