Siemens SINAMICS S210 - Actual Value;Setpoint Preprocessing no Longer Synchronous; Communication Error between the Control Unit and Power Module; Power Unit: Current Increasing too Quickly

Acknowledge: IMMEDIATELY
Cause: The following applies for CU31x and CUA31:
More than one setpoint telegram was not able to be transferred to the power unit module.
Remedy: The following applies for CU31x and CUA31:
Check the interface (adjustment and locking) to the power unit module.
A30073 (N) Actual value/setpoint preprocessing no longer synchronous
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: Communication with the power unit module is no longer in synchronism with the current control cycle.
Remedy: Wait until synchronization is re-established.
Reaction upon N: NONE
Acknowl. upon N: NONE
F30074 (A) Communication error between the Control Unit and Power Module
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: Communications between the Control Unit (CU) and Power Module (PM) via the interface no longer possible. The CU may
have been withdrawn or is incorrectly inserted.
Fault value (r0949, interpret hexadecimal):
0 hex:
- a Control Unit with external 24 V supply was withdrawn from the Power Module during operation.
- with the Power Module switched off, the external 24 V supply for the Control Unit was interrupted for some time.
1 hex:
The Control Unit was withdrawn from the Power Module during operation, although the encoderless safe motion monitoring
functions are enabled. This is not supported. After re-inserting the Control Unit in operation, communications to the Power
Module no longer possible.
20A hex:
The Control Unit was inserted on a Power Module, which has another code number.
20B hex:
The Control Unit was inserted on a Power Module, which although it has the same code number, has a different serial
number.
601 hex:
The Control Unit was inserted on a Power Module, whose power/performance class (chassis unit) is not supported.
Remedy: Reinsert the Control Unit (CU) or the Control Unit Adapter (CUAxx) onto the original Power Module and continue operation.
If required, carry out a POWER ON for the CU and/or the CUA.
Reaction upon A: NONE
Acknowl. upon A: NONE
F30080 Power unit: Current increasing too quickly
Message value: Fault cause: %1 bin
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
