165065 Result field weakening speed < rated speed
Scan
Softkey "Calculate equivalent circuit diagram data (MSD only)"
Effect
The equivalent circuit diagram data have not been calculated, the field weakening speed (MD 1142 and 2142) can
now be modified manually.
Explanation
The calculated field weakening speed is smaller than the rated speed (MD 1400 and 2400). This WarnNote is dis-
played if rated voltage plus the voltage drop at the series reactor exceed 400V.
Remedy
Correct value of "field weakening speed" manually.
Note
Applies as from SW 5.4
165066 Current controller gain (MD 1120) not calculable
Scan
Softkey "Calculate controller data (FDD only)"
Effect
The controller data have been calculated, the machine data concerned has been given a suitable default value.
Explanation
The calculated current controller gain is < 0.
Remedy
If necessary, correct value and repeat function.
Note
Applies as from SW 5.4
165067 Default value (MD x15) cannot be calculated
Scan
Softkey "Calculate controller data (MSD only)"
Effect
The controller data have been calculated, the machine data concerned has been given a suitable default value.
The result calculated was a default value  0.
Explanation
Remedy
If necessary, correct value and repeat function.
Note
Applies as from SW 5.4
165068 Magnetizing reactance (MD x14) not allowed
Scan
Softkey "Calculate controller data (MSD only)"
Effect
The controller data have been calculated, the machine data concerned has been given a suitable default value.
Explanation
The value 0 has been entered for the magnetizing reactance (MD1141 and MD 2141).
Remedy
If necessary, correct value and repeat function.
Note
Applies as from SW 5.4
165069 Leakage reactance (MD x139/MD x140) not allowed
Scan
Softkey "Calculate controller data (MSD only)"
Effect
The controller data have been calculated, the machine data concerned has been given a suitable default value.
Explanation
The value 0 has been entered for one of the leakage reactances (MD 1139, 1140, 2139, 2140).
Remedy
If necessary, correct value and repeat function.
Note
Applies as from SW 5.4
165070 Rated frequency (MD x134) not allowed
Scan
Softkey "Calculate controller data (MSD only)"
Effect
The controller data have been calculated, the machine data concerned has been given a suitable default value.
Explanation
The value 0 has been entered for the rated frequency (MD 1134 and MD 2134).
Remedy
If necessary, correct value and repeat function.
Note
Applies as from SW 5.4
