Fault/Alarm
A0139: It indicates an interruption in the
(2)
Offline Profibus DP communication between the Profibus DP
Interface network master and the inverter.
A0140: It indicates an error in the access to the
(2)
Profibus DP Profibus DP communication module
Module Access data.
Error
F0150: Overspeed fault.
Motor Overspeed It trips when the actual speed exceeds
the value of P0134 x
more than 20 ms.
F0151: FLASH Memory Module (MMF-01) fault.
FLASH Memory
Module Fault
A0152: This alarm indicates that the internal air
High Internal Air temperature is too high.
Temperature Note:
It can be disabled by setting
P0353 = 1 or 3.
F0153: It indicates internal air overtemperature
Internal Air fault.
Overtemperature
F0156: The temperature sensors located in the
Undertemperature IGBTs or in the rectifier detected a low
temperature, below
-30 °C ( -22 °F), fault.
F0157: There was a problem during the
Parameter Table initialization, during the parameter table
Data Loss loading routine. Some recent parameter
modifications may have been lost.
F0158: There was a problem during the
Parameter Table initialization, during the parameter table
Fault loading routine. All the parameters were
lost and the factory settings were loaded.
A0159: Incompatible HMI
Incompatible HMI
F0160: STO function (Safe Torque Off) relay fault.
Safety Stop Relays
A0163: It indicates that the AI1 current
AI1 Broken Cable (4-20 mA or 20-4 mA) reference is out of
the 4 to 20 mA range.
A0164: It indicates that the AI2 current (4-20 mA or
AI2 Broken Cable 20-4 mA) reference is out of the 4 to 20
mA range.
A0168: Difference between Speed Reference and
Speed Error too Effective Speed greater than the setting
High in P0360.
F0169: Difference between Speed Reference and
Speed Error too Effective Speed greater than the setting in
High P0360 for longer than P0361.
A0170: The STO function (Safe Torque Off) is
Safety Stop active.
