10.2.2. NXS/P information
Vacon NXS/P-drive has a capacity to save last 30 faults codes and show them on dis-
play of control panel, if desired.
There is always a reason for the tripping of the drive and it should be solved before to
proceed in an operation and to avoid damages in equipment.
Fault codes from F50 and above are generated from the application. They are not sys-
tem software fault codes. Some fault codes for special system software or applications
do not have troubleshooting instruction. Instructions for such codes are available in
respective software manual.

in “Fault codes in NXL unit.” on page 21 covers fault codes in software versions until
