Message value: Fault cause: %1, motor data set: %2 Drive object: SERVO, VECTOR Reaction: OFF2 Acknowledge: IMMEDIATELY Cause: The armature short-circuit is incorrectly parameterized. Fault value (r0949, interpret decimal): Low word: Motor data set number High word: Cause: 1: A permanent-magnet synchronous motor has not been selected. 101: External armature short-circui t: Output (r1239.0) not connected up. 102: External armature short-circuit with c ontactor feedback signal: No feedback signal connected (BI:p1235). 103: External armature short-circuit withou t contactor feedback signal: Delay time when opening (p1237) is 0. 201: Internal voltage protection: The maximum output current of the Motor Module (r0289) is less than 1.8 * motor short-circuit current (r0331). 202: Internal voltage protection: A Motor Module in booksize format is not being used. 203: Internal voltage protection: The motor short-ci rcuit current (p0320) is greater than the maximum motor current (p0323). 204: Internal voltage protection: The activation (p1231 = 4) is not given for all motor data sets with synchronous motors (p0300 = 2xx, 4xx). SINAMICS-Alarms Remedy: Re cause 1: - an armature short-circuit / voltage protection is only permissible for permanent-magnetic synchronous motors. The highest position of the motor type in p0300 must either be 2 or 4. Re cause 101: - the contactor for the external armature short-ci rcuit configuration should be controlled using output signal r1239.0. The signal can, e.g. be connected to an output terminal BI: p0738. Before this fault can be acknowledged, p1231 must be set again. Re cause 102: - if the external armature short-circuit with cont actor feedback signal (p1231 = 1) is selected, this feedback signal must be connected to an input termin al (e.g. r722.x) and then connected to BI: p1235. - alternatively, the external armature short-circ uit without contactor feedback signal (p1231 = 2) can be selected. Re cause 103: - if the external armature short-circuit without contactor feedback signal (p1231 = 2) is selected, then a delay time must be parameterized in p1237. This time must always be greater than the actual contactor opening time, as otherwise the Motor Module would be short-circuited! Re cause 201: - a Motor Module with a higher maximum current or a motor with a lower short-circuit current must be used. The maximum Motor Module current must be higher than 1.8 * short-circuit current of the motor. Re cause 202: - for internal voltage protection, us e a Motor Module in booksize format. Re cause 203: - for internal voltage protection, onl y use short-circuit proof motors. Re cause 204: - The internal voltage protection must either be activated for all motor data sets with synchronous motors (p0300 = 2xx, 4xx) (p1231 = 3) or it must be de-activated for all motor data sets (p1231 not equal to 3). This therefore ensures that the protec tion cannot be accidentally wi thdrawn as a result of a data set changeover. The fault can only be acknowledged if this c ondition is fulfilled.
