What it means
F01002 is raised when the drive detects an internal error in its own software. The manuals for the G120, G120XA, G130, G150, S120 and S150 describe this code with the same cause and the same remedy, so one description covers all of them. While the fault is active the drive coasts down and must be acknowledged before it will start again.
Why it appears
- The drive software has run into an internal error.
What to check
- Carry out a POWER ON: switch all components off and back on again.
- Upgrade the firmware to a later version.
- Contact Technical Support if the fault occurs again.
Reading the message value
- The drive stores the fault value of this event in r0949; the manual says to interpret it hexadecimal.
- The note attached to this value reads:
Only for internal Siemens troubleshooting.
No bit breakdown for technicians is printed for this code.
Parameters the manual names
- r0949 — fault value of this event: read it out hexadecimal if Technical Support asks for it; the manual reserves it for internal Siemens troubleshooting.
Acknowledging and restarting
Acknowledge the fault immediately once you have carried out the POWER ON and, if needed, the firmware upgrade — the drive permits immediate acknowledgement for this code. After the acknowledgement the fault message is cleared and the drive can be given a new start command.
