F30105 PU: Actual value sensing fault
Message value: -
Message class: Power electronics faulted (5)
Drive object: B_INF, VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: At least one incorrect actual value channel was detected on the Power Stack Adapter (PSA).
The incorrect actual value channels are displayed in the following diagnostic parameters.
Remedy: Evaluate the diagnostic parameters.
If the actual value channel is incorrect, check the components and if required, replace.
F30314 Power unit: 24 V power supply overloaded by PM
Message value: -
Message class: Supply voltage fault (undervoltage) (3)
Drive object: VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The 24 V power supply through the Power Module (PM) is overloaded.
An external 24 V power supply via X124 on the Control Unit is not connected.
Remedy: Connect an external 24 V power supply via X124 at the Control Unit.
A30315 (F) Power unit: 24 V power supply overloaded by PM
Message value: -
Message class: Supply voltage fault (undervoltage) (3)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: The 24 V power supply through the Power Module (PM) is overloaded.
An external 24 V power supply via X124 on the Control Unit is not connected.
Remedy: Connect an external 24 V power supply via X124 at the Control Unit.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
A30502 Power unit: DC link overvoltage
Message value: %1
Message class: DC link overvoltage (4)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: The power unit has detected overvoltage in the DC link on a pulse inhibit.
- device connection voltage too high.
- line reactor incorrectly dimensioned.
Alarm value (r0949, interpret decimal):
DC link voltage [1 bit = 100 mV].
See also: r0070 (Actual DC link voltage)
Remedy: - check the device supply voltage (p0210).
- check the dimensioning of the line reactor.
