Dear akyilmaz,

please check your configuration regarding the motor temperature evaluation according function diagramm -491- in the Masterdrives MC compendium.
The link to the compendiumMasterdrives MC1.6: http://support.automation.siemens.com/WW/view/en/23660019
P830 blocks destinated faults only, no alarms.
For I²t calculation (no KTY, Thermistor ...), put in the parameter p383 the correct thermal time constant of the motor in seconds.
The time constant of the motor can be estimated for induction motors referring the frame size and the no. of poles according the table in the p383 parameters description (Masterdrives MC compendium).
