Power Unit: Configuration Not Supported - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
Cause: The hardware current limitation in the relevant phase (see A30031, A30032, A30033) has responded too often. The
number of times the limit has been exceeded depends on the design and type of power unit.
For infeed units, the following applies:
- closed-loop control is incorrectly parameterized.
- load on the infeed is too high.
- Voltage Sensing Module incorrectly connected.
- line reactor missing or the incorrect type.
- power unit defective.
The following applies to Motor Modules:
- closed-loop control is incorrectly parameterized.
- fault in the motor or in the power cables.
- the power cables exceed the maximum permissible length.
- motor load too high
- power unit defective.
Fault value (r0949, interpret binary):
Bit 0: Phase U
Bit 1: Phase V
Bit 2: Phase W
Remedy: For infeed units, the following applies:
- check the controller settings and reset and identify the controller if necessary (p0340 = 2, p3410 = 5)
- reduce the load and increase the DC-link capacitance or use a higher-rating infeed if necessary
- check the connection of the optional Voltage Sensing Module
- check the connection and technical data of the line reactor
- check the power cables for short-circuit or ground fault.
- replace power unit.
The following applies to Motor Modules:
- check the motor data.
- check the motor circuit configuration (star-delta).
- check the motor load.
- check the power cable connections.
- check the power cables for short-circuit or ground fault.
- check the length of the power cables.
- replace power unit.
230020 <location>Power unit: Configuration not supported
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A configuration is requested that is not supported by the power unit.
Fault value (r0949, interpret hexadecimal):
0:
Autonomous operation is requested but is not supported.
1:
The requested DRIVE-CLiQ timing is not permissible.
2:
A PM260 has ben detected with PS-ASIC version 2. This combination is not supported.
Remedy: Re fault value = 0:
If internal voltage protection is active (p1231 = 3), de-activate it if necessary.
Re fault value = 1:
Perform a firmware update in the Control Unit or change the DRIVE-CLiQ topology.
Re fault value = 2:
Replace the power unit with a PM260 with PS-ASIC version 3 (or higher).
