Message value: Drive object: SERVO Reaction: OFF2 (NONE) Acknowledge: IMMEDIATELY Cause: Either the direction of the rotating field or the enc oder actual value has an incorrect sign. The motor data identification automati cally changed the actual value inversion (p0410) in order to correct the control sense. This can result in a direction of rotation change. To acknowledge this fault, the correctness of the direction of rotation must first be acknowledged with p1910 = -2. SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Remedy: Check the direction of rotation, also for t he position controller, if one is being used. If the direction of rotation is correct, the following applies: No additional measures are required (e xcept p1910 = -2 and acknowledge fault).
