Pasos oficiales de solución de problemas

Message value: %1 Drive object: SERVO, VECTOR Reaction: OFF1 (NONE, OFF2, OFF3) Acknowledge: IMMEDIATELY Cause: When powered down, the currently effective motor encoder was moved through a distance greater than was parameterized in the tolerance window. It is possible that there is no longer any reference between the mechanical system and encoder. Note: Here, only the motor encoder in the currently effective drive data set is monitored. The currently effective drive data set is displayed in x = r0051 and the corresponding motor encoder is specified in p0187[x]. Fault value (r0949, interpret decimal): Deviation (difference) to the last encoder position in increments of the absolute value after the measuring gear - if one is being used. The si gn designates the trav ersing direction. Note: The deviation (difference) found is also displayed in r2724. See also: p2722 (Load gear, position tracking toler ance window), r2724 (Load gear position difference) Remedy: Reset the position tracking as follows: - select encoder commissioning (p0010 = 4). - reset position tracking, position (p2720.2 = 1). - de-select encoder commissioning (p0010 = 0). The fault should then be acknowledged and, if neces sary, the absolute encoder adjusted (p2507). See also: p0010, p2507
