data identification
failure
• Motor data identification
failed
• Alarm value = 0: Load is
missing
• Alarm value = 1: Current
limit value reached during
identification.
• Alarm value = 2: Identified
stator resistance less than
0.1% or more than 100%.
• Alarm value = 3: Identified
rotor resistance less than
0.1% or more than 100%.
• Alarm value = 4: Identified
stator reactance less than
50% or more than 500%.
• Alarm value = 5: Identified
main reactance less than
50% or more than 500%.
• Alarm value = 6: Identified
rotor time constant less than
10 ms or more than 5s.
• Alarm value = 7: Identified
total leakage reactance less
than 5% or more than 50%.
• Alarm value = 8: Identified
stator leakage reactance
less than 25% or more than
250%.
• Alarm value = 9: Identified
rotor leakage reactance less
than 25% or more than
250%.
• Alarm value = 20: Identified
IGBT ON-voltage less than
0.5 or more than 10V.
• Alarm value = 30: Current
controller at voltage limit.
• Alarm value = 40:
Inconsistency of identified
data set, at least one
identification failed.
Percentage values based on
impedance
Zb = Vmot,nom / sqrt(3) /
Imot,nom.
0: Check if the motor is
connect to the SED2.
1-40: Check if the motor data in
P0304 to P0311 are correct.
Check the type of motor wiring
required (star, delta).
