Hello, double click on the fault message will open the help to the fault or you search the fault in the Sinamics S120 List Manual If the alarm windows in scout display no name for the DO then you should upload the Drive Configuration to your project. F07900 (N, A) Drive: Motor blocked/speed controller at its limit Message value: - Message class: Application / technological function faulted (17) Drive object: HLA, SERVO, SERVO_AC, SERVO_I_AC Reaction: OFF2 (NONE, OFF1, OFF3, STOP2) Acknowledge: IMMEDIATELY Cause: Motor has been operating at the torque limit longer than the time specified in p2177 and below the speed threshold in p2175. This signal can also be initiated if the speed actual value is oscillating and the speed controller output repeatedly goes to its limit. See also: p2175, p2177 Remedy: - check that the motor can freely move. - check the effective torque limits (r1538, r1539). - check the parameter, message "Motor blocked" and if required, correct (p2175, p2177). - check the inversion of the actual value (p0410). - check the motor encoder connection. - check the encoder pulse number (p0408). - for SERVO with encoderless operation and motors with low power ratings (< 300 W), increase the pulse frequency (p1800). - after de-selecting the "Basic positioner" (EPOS) function mode, check the motoring (p1528) and regenerative (p1529) torque limit and modify again. Reaction upon N: NONE Acknowl. upon N: NONE Reaction upon A: NONE Acknowl. upon A: NONE Regards Christoph |
