The line fuse for Line n has blown.
• Check the fuse and replace if necessary.
• Verify that the line fuse wiring harness for line 1 is not damaged and
is connected to P7 on the converter gate firing board. Replace the
wiring harness if necessary.
• If this problem persists, replace the converter gate firing board.

Coast
The AC line voltage has exceeded 565V (for 400V class drives) or 815V
(for 600V class drives), which corresponds to the nominal bus voltage of
799V DC (for 400V class drives) or 1150V DC (for 600V class drives). This
fault is intended to protect the capacitor bank from an overvoltage
condition especially if a 400V class drive is inadvertently placed in a
600V system.
• Verify the incoming line voltage.
