14.13 INCOMPATIBLE MAIN SOFTWARE VERSION (F0151)
When the inverter is energized, the main software version stored in the non-volatile area (EEPROM) is compared
to the version stored in the secondary microcontroller flash memory (plug-in module). This comparison is done
to check the integrity and compatibility of the stored data. Those data are stored to allow copying the parameter
configuration (standard user, 1 and 2) between inverters using the CFW500-MMF and with the inverter de-energized.
If the versions are not compatible, fault F0151 will occur.
For further information on possible causes for the occurrence of fault F0151, refer to the CFW500-MMF accessory
guide.
14.14 PULSE FEEDBACK FAULT (F0182)
When the dead time compensation is active in P0397 (refer to chapter 8 AVAILABLE MOTOR CONTROL TYPES
on page 8-1) and the pulse feedback circuit has some defect, fault F0182 will occur.
NOTE!
When this fault occurs, contact WEG.
14.15 FAULT HISTORY
The inverter is able to store a set of data on the last three faults occurred, such as: fault number, current (P0003), DC
link voltage CC (P0004), output frequency (P0005), power module temperature (P0030) and logical status (P0680).
