4 Faults and alarms
4.2 List of faults and alarms
SINAMICS DCM
982 List Manual (LH8), 02/2015, 6RX1800-0ED76
Remedy: The power unit only supports the following cycles:
62.5 µs, 125 µs, 250 µs and 500 µs
For fault value = 0:
Set a permitted current control cycle.
For fault value = 1:
Set a permitted DRIVE-CLiQ cycle.
Re fault value = 2, 3:
Contact the manufacturer (you may have an incompatible firmware version).
F30071 No new actual values received from the power unit
Message value: -
Message class: Internal (DRIVE-CLiQ) communication error (12)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The number of actual value telegrams from the power unit module that have failed has exceeded the permissible
number.
Remedy: Check the interface (adjustment and locking) to the power unit module.
F30072 Setpoints are no longer being transferred to the power unit
Message value: -
Message class: Internal (DRIVE-CLiQ) communication error (12)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: OFF2
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: -
Message class: Internal (DRIVE-CLiQ) communication error (12)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
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
Message class: Internal (DRIVE-CLiQ) communication error (12)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
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CU may have been withdrawn or is incorrectly inserted.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- a Control Unit with external 24 V supply was withdrawn from the Power Module during operation.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.
