What it means
F07490 is raised by the basic positioning function (EPOS): the axis was traversing when the enable signal was withdrawn. For a standard assignment, the withdrawn enable signals leave the drive in the switching on inhibited
state. The manuals for the G130, G150, S120 and S150 describe this fault identically, and no message value is given. Depending on the drive configuration, the same condition can also be output with no drive reaction (N).
Why it appears
- For a standard assignment, the enable signals were withdrawn, and another fault may have occurred as a result of that withdrawal.
- For a standard assignment, the drive is in the
switching on inhibited
state.
What to check
- Set the enable signals again (for a standard assignment).
- If a fault appeared before this one, find and correct the cause of that first fault and then deal with the resulting one (for a standard assignment).
- Check the assignment that enables the basic positioning function (EPOS).
Acknowledging and restarting
The drive is brought to a standstill (OFF1; OFF2 or OFF3 can apply depending on the configuration). Once the enable signals are present again or the fault that occurred first has been corrected, acknowledge the fault and switch the drive on again. When the message is configured with no reaction (N), it triggers neither a reaction nor an acknowledgement.
The same on every family
Every manual that describes F07490 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF1 (OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2829 |
| G130, G150 | OFF1 (OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1565 |

Questions technicians ask
What does SINAMICS fault F07490 mean?
The basic positioning function (EPOS) was traversing the axis when the enable signal was withdrawn. For a standard assignment, the drive then sits in the switching on inhibited state.
How do I clear fault F07490?
Set the enable signals again, or first correct the fault that occurred before this one, and check the assignment that enables the basic positioning function. Then acknowledge the fault and switch the drive on again.
Why does F07490 appear together with another fault?
For a standard assignment, another fault may have occurred as a result of the enable signals being withdrawn. Find the fault that appeared first and correct its cause.
Does F07490 always stop the drive?
No. Depending on the configuration, the same condition can also be output with no drive reaction (N); in that case neither a reaction nor an acknowledgement applies.
