Siemens SINAMICS S120 Function Manual page 761

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.
Infeed faulted
The infeed is faulty or has failed. Check the infeed and the surroundings (line supply, filters,
reactors, fuses, etc.). Check the infeed control.
Braking controller faulted
The internal or external Braking Module is faulted or overloaded (temperature). Check the
connection/state of the Braking Module. Comply with the permissible number of braking
operations and their duration.
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.
