Issue 01/06Faults and Alarms
F0041 Failure, motor data identification | STOP II |
Quit
Refer to F0001
Cause
Motor data identification run unsuccessful (refer to fault value r0949):
-r0949 = 0: Load missing.
-r0949 = 1: Current limit was reached during the identification run.
-r0949 = 2: Identified stator resistance less than 0.1% or greater than 100%.
-r0949 = 3: Identified rotor resistance less than 0.1% or greater than 100%.
-r0949 = 4: Identified stator reactance less than 50% or greater than 500%
-r0949 = 5: Identified magnetizing reactance less than 50% or greater than 500%
-r0949 = 6: Identified rotor time constant less than 10ms or greater than 5s
-r0949 = 7: Identified total leakage reactance less than 5% or greater than 50%
-r0949 = 8: Identified stator leakage reactance less than 25% or greater than 250%
-r0949 = 9: Identified rotor leakage reactance less than 25% or greater than 250%
-r0949 = 20: Identified IGBT response voltage less than 0.5 or greater than 10V
-r0949 = 30: Current controller at voltage limit value
-r0949 = 40: Identified data set inconsistent; at least one identification run unsuccessful
NOTE
Percentage values based on the impedence Zb = Vmot,rated / sqrt(3) / Imot,rated
Diagnosis & Remedy
Please check the following:
-r0949 = 0: Is the motor connected to the inverter ?
-r0949 =
-r0949 =
F0042 Fault/error when optimizing the speed controller | STOP II |
Quit
Refer to F0001
Cause
Automatic data identification run unsuccessful (refer to fault value r0949):
-r0949 = 0: Time slice overflow while waiting for a stable speed
-r0949 = 1: No matching/appropriate value when reading
F0051 Parameter EEPROM fault | STOP II |
Quit
Refer to F0001
Cause
-read or write operation while saving parameters in the EEPROM was unsuccessful.
Diagnosis & Remedy
-reset to factory setting and then
-if required, change the drive
F0052 Power stack fault | STOP II |
Quit
Refer to F0001
Cause
-read error, power data or invalid power module data.
Diagnosis & Remedy
-change the drive
F0053 I/O EEPROM fault | STOP II |
Quit
Refer to F0001
Cause
-fault with I/O EEPROM read operation or invalid data.
Diagnosis & Remedy
Please check the following:
-check I/O data and if required repeat the operation
-the installation of the I/O module in the inverter if required, replace the I/O module
