6.22 Fault Reset (AKD_Fault_Reset)
6.22.1 Description
This instruction will attempt to clear faults. The drive must be disabled before executing this instruction.
In most cases, AKD_Shutdown_Reset should be used instead, as it disables the drive and checks that
faults have been cleared successfully.
The AKD_Fault_Reset instruction execution may take multiple scans to execute because it requires trans-
mission of a message to the motion module and time for the drive to execute the command. The Done (.DN)
bit is not set immediately, but only after the faults have been cleared.
