Fault/warning
With bit 5 in the status word, the inverter signals a possible fault or warning. The result
of a
fault
is always that the frequency inverter is no longer ready for operation. A
warn-
ing
can occur temporarily without affecting the operating behavior of the inverter. This
is why you should also evaluate status bit 1
inverter ready
to exactly filter a fault (require-
ment: line voltage ON).
Status word 1
Status word 1 contains the status information in the basic status block and the
unit status
or the
fault number
in the higher-level status byte. The unit status is displayed when fault
bit = 0, and the fault number is displayed in case of a fault (fault bit = 1). The fault bit is
reset by resetting the fault, and the current unit status is displayed again. You find infor-
mation on the meaning of the fault numbers and the device status in the system manual
or in the MOVITRAC
®
B operating instructions.
