Code 207900: <location>Drive: Motor locked/speed controller at its limit

Message value: Drive object: SERVO Reaction: OFF2 (NONE, OFF1, OFF3, STOP1, STOP2) Acknowledge: IMMEDIATELY Cause: Motor has been operating at the torque limit longer than the time specified in p2177 and below the speed threshold set 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 SINAMICS-Alarms Remedy: - check that the motor can freely rotate. - check the torque limit: For a positive direction of rotation r1538, for a negative direction of rotation r1539. - check the parameter, message "Motor locked" 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 basic positioning, check t he torque limits when motoring (p1528) and when regenerating (p1529).
