230073 <location>Actual value/setpoint preprocessing no longer synchronous
to DRIVE-CLiQ
Message -
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The following applies for CU31x and CUA31:
Communications to the power unit module are no longer in synchronism with DRIVE-CLiQ.
Remedy: The following applies for CU31x and CUA31:
Wait until synchronization is re-established.
230074 <location>Communications error to the power unit module
Message -
value:
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: Communication is not possible with the power unit via the plug contact.
Remedy: The following applies for CU31x and CUA31:
Either replace the CU board or the power unit. You must check which of the two components must be
replaced by replacing one and then the other component; if neither are available then both compo-
nents must be returned.
230105 <location>PU: Actual value sensing fault
Message -
value:
Drive object: All objects
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.
230502 <location>Power unit: DC link voltage, overvoltage
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The power unit has detected overvoltage in the DC link with a pulse inhibit.
- device supply voltage too high.
- line reactor incorrectly dimensioned.
Fault 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.
See also: p0210 (Drive unit line supply voltage)
230600 <location>SI MM: STOP A initiated
Message %1
value:
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
