What it means
F30070 means that a cycle has been requested which the connected power unit does not support. The power unit only supports the cycles 62.5 µs, 125 µs, 250 µs and 500 µs. Which cycle or timing problem the drive has detected is stored as a fault value in r0949 (interpret hexadecimal): 0 stands for a rejected current control cycle, 1 for a rejected DRIVE-CLiQ cycle, and 2 or 3 for an internal timing problem. The manual describes this fault identically for SINAMICS G130, G150, S120 and S150.
Why it appears
- The drive requests a cycle that is not supported by the power unit. Only the cycles 62.5 µs, 125 µs, 250 µs and 500 µs are supported, so the requested cycle lies outside this set.
- Depending on the fault value, either the current control cycle or the DRIVE-CLiQ cycle is not supported, or an internal timing problem exists (see the fault value list below).
What to check
- Read the fault value in r0949 (interpret hexadecimal) to determine which cycle the power unit rejected or which timing problem is present.
- Check that the requested cycle is one of the cycles the power unit supports: 62.5 µs, 125 µs, 250 µs or 500 µs.
- For fault value 0: set a permitted current control cycle.
- For fault value 1: set a permitted DRIVE-CLiQ cycle.
- For fault value 2 or 3: contact the manufacturer — you may have an incompatible firmware version.
Reading the message value
- The message value %1 carries the fault value, which the drive stores in r0949; interpret it hexadecimal.
- 0: The current control cycle is not supported.
- 1: The DRIVE-CLiQ cycle is not supported.
- 2: Internal timing problem (clearance between RX and TX instants too low).
- 3: Internal timing problem (TX instant too early).
Parameters the manual names
- r0949 — read the fault value of F30070 here, interpreted hexadecimal, to see whether the current control cycle (0), the DRIVE-CLiQ cycle (1) or an internal timing problem (2, 3) is present.
Acknowledging and restarting
The fault response switches the drive off (OFF2): the motor coasts down, and the drive must be acknowledged before it will start. After you have set a cycle the power unit supports, acknowledge the fault immediately and restart the drive. If the unsupported cycle is still requested, F30070 is raised again.
The same on every family
Every manual that describes F30070 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 | IMMEDIATELY | Error in the parameterization / configuration / commissioning procedure (18) | Power Module | SINAMICS S120, S150 List Manual · p. 2963 |
| G130, G150 | OFF2 | IMMEDIATELY | Error in the parameterization / configuration / commissioning procedure (18) | Power Module | SINAMICS G130, G150 List Manual · p. 1670 |

Questions technicians ask
What does fault F30070 mean on a SINAMICS G130, G150, S120 or S150?
The drive has requested a cycle that the power unit does not support. Only the cycles 62.5 µs, 125 µs, 250 µs and 500 µs are supported.
How do I fix F30070?
Read the fault value in r0949 (interpret hexadecimal). For fault value 0 set a permitted current control cycle, for fault value 1 set a permitted DRIVE-CLiQ cycle, and for fault value 2 or 3 contact the manufacturer, as you may have an incompatible firmware version.
What do fault values 2 and 3 of F30070 mean?
Both indicate an internal timing problem: value 2 means the clearance between the RX and TX instants is too low, value 3 means the TX instant is too early. The remedy is to contact the manufacturer.
Can F30070 be acknowledged immediately?
Yes, the fault is acknowledged immediately once the cycle has been corrected, and the drive can then be restarted. If the unsupported cycle is still requested, the fault comes back.
