What it means
F01031 is raised when, with the "OFF in REMOTE" mode active, no sign-of-life has been received within 3 seconds. The manuals for G130, G150, S120 and S150 describe the fault with the same cause, and no message value is supplied with it. The affected drive object is switched off along the response the table shows for it, and the message must be acknowledged immediately before the drive can run again.
Why it appears
- While the "OFF in REMOTE" mode is active, no sign-of-life reached the drive within 3 seconds.
What to check
- Check that the data cable is properly connected at the serial interface for the Control Unit (CU) and at the operator panel.
- Check the data cable that runs between the Control Unit and the operator panel.
Acknowledging and restarting
The fault must be acknowledged immediately. Once the data cable fault has been found and removed, an immediate acknowledgement is all the manual describes for clearing F01031; no further reset step is given.
