51 PXIO EEPROM • Problem on PX-I/O EEPROM
• Power down and then power up again
• Return to factory settings
(see
00.45
)
52 PXIO power • Overload of the PX-I/O power supply
• Loss of 24 V detected by the option
• Check the current consumption
• Make sure there has not been a temporary overload of
the 24 V
53 PXIO CLOCK
• Problem on the real-time clock of the
PX-I/O
• Power down and then power up again
• Set the time again
54 PXIO COMM
• Communication problem between the
drive and the PX-I/O
• Power down the drive, then check that the option
is positioned correctly
56 IGBT V • Trip on an IGBT (V)
• Reduce the motor load, the cycle, the switching frequency
(see
00.12
or
05.18
), and lengthen the acceleration
ramp (see
00.03
or
02.11
) and deceleration ramp
(see
00.04
or
02.21
).
57 IGBT W • Trip on an IGBT (W)
• Reduce the motor load, the cycle, the switching frequency
(see
00.12
or
05.18
), and lengthen the acceleration
ramp (see
00.03
or
02.11
) and deceleration ramp
(see
00.04
or
02.21
).
58 Th IGBT V
• IGBT (V) overheating, ventilation
problem, ambient temperature too
high
• Load too great
• Check the ambient temperature
• Check the drive load level
• Check that all the fans are working
• Check the state of the door filters
• Check the frequency and temperature derating of the
drive (see Installation manual)
No.
