What it means
F40004 reports that a fault has occurred at the drive object connected at DRIVE-CLiQ socket X104. The code acts as a first-fault message: the drive stores the first fault that has occurred for this drive object as the fault value, which you read in r0949 as a decimal number.
Why it appears
- A fault has occurred at the drive object connected at DRIVE-CLiQ socket X104.
What to check
- Evaluate the fault buffer of the drive object specified by the message.
- Read the fault value in r0949 as a decimal number; it names the first fault that has occurred for this drive object, and the remedy for that fault applies.
Reading the message value
- The drive stores the fault value in r0949; interpret it as a decimal number.
- The manual decodes the value only as the first fault that has occurred for this drive object — no bit-by-bit decoding is given.
Parameters the manual names
- r0949 — fault value: read it as a decimal number to identify the first fault that has occurred for the drive object at X104.
Acknowledging and restarting
Acknowledge the fault immediately. The fault itself triggers no automatic response from the drive; it points to the first fault of the drive object at X104, which you find by evaluating that object's fault buffer.
