Table 4-5. Drive Fault Bit Description
Key: C: Performs controlled stop
K: Performs motion kill – quick stop. Possible instant de-energise depending on fault source
R: Recoverable without power cycle
T: Terminal (requires power cycle or repair before drive will energise/operate again)
Drive Fault Byte Reporting
In exactly the same way as the status variable, the drive fault status can be reported a byte
at a time, using DFn within a read command.
