30.35 FB TimeOut (fieldbus time out)
Time delay before a communication break with a fieldbus is declared. Depending on the setting of
ComLossCtrl (30.28)
either F528 FieldBusCom [FaultWord2 (9.02) bit 11] or A128 FieldBusCom
[
AlarmWord2 (9.07) bit 11] is set.
The communication fault and alarm are inactive, if
FB TimeOut (30.35) is set to 0 ms.

30.36 SpeedFbFltMode (speed feedback fault mode)
SpeedFbFltMode (30.36)
determines the reaction of all faults of trip level 3:
0 =
CoastStop The firing pulses are immediately set to 150 degrees to decrease the armature current.
When the armature current is zero the firing pulses are blocked, the contactors are
opened, field exciter and fans are stopped.
1 =
DynBraking dynamic braking
Note:
SpeedFbFltMode (30.36)
does not apply to communication faults.

Group 31: Motor temperature
31.01 M1ModelTime (model time constant)
Thermal time constant for motors with fan/forced cooling. The time within the temperature rises to 63% of
its
nominal value.
The motor thermal model is blocked, if
M1ModelTime (31.01) is set to zero.
The value of
Mot1TempCalc (1.20) is saved at power down of the drives electronics. Energizing the drives
electronics the very first time the motor's ambient temp
erature is set to 30°C.
WARNING! The model does not protect the motor if it is not properly cooled e.g. due to dust and dirt.
