4 Faults and alarms
4.1 Overview of faults and alarms
Table 4-4 Message classes and coding of various diagnostic interfaces
Text of the message class (number according to PROFIdrive)
Cause and remedy.
Hardware/software errors (1)
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 (2)
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 (3)
An electronics supply voltage fault (48 V, 24 V, 5 V ...) was detected.
Check the wiring. Check the voltage level.
DC-link overvoltage (4)
The DC-link voltage has assumed an inadmissibly high value. Check
the dimensioning of the system (line supply, reactor, voltages). Check
the infeed settings.
Power electronics fault (5)
An impermissible operating state of the power electronics was
detected (overcurrent, overtemperature, IGBT failure ...). Check
compliance with the permissible load cycles. Check the ambient
temperatures (fan).
Overtemperature of the electronic component (6)
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 (7)
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 (8)
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 higher-level controller faulted (9)
The communication to the higher-level controller (internal coupling,
PROFIBUS, PROFINET ...) is faulted or interrupted. Check the state
of the higher-level controller. Check the communication
connection/-wiring. Check the bus configuration/cycles.
Safety monitoring channel has detected an error (10)
A safe operation monitoring function has detected an error.
Actual position/speed value incorrect or not available (11)
An illegal signal state was detected while evaluating the encoder
signals (track signals, zero marks, absolute values ...). Check the
encoder / state of the encoder signals. Observe the maximum
permissible frequencies.
