Código 207493: <location>LR: Overflow of the value range for position actual value
Descripción del problema y advertencia de seguridad
El Siemens SINUMERIK 840D CNC ha desencadenado una alarma crítica <location>LR: Overflow of the value range for position actual value. Se requiere la atención inmediata de un operador calificado o técnico de mantenimiento para evitar daños secundarios al equipo o piezas estropeadas durante el ciclo de fabricación. Asegúrese siempre de seguir los procedimientos de seguridad estándar y LOTO antes de acceder a los armarios eléctricos.

Message value: %1 Drive object: SERVO, VECTOR Reaction: OFF1 (OFF2, OFF3) Acknowledge: IMMEDIATELY Cause: The value range (-2147483648... 2147483647) for the po sition actual value representation was exceeded. When the overflow occurs, the "referenced" or " adjustment absolute measur ing system" status is reset. Fault value (r0949, interpret decimal): 1: The position actual value (r2521) has exceeded the value range. 2: The encoder position actual va lue Gn_XIST2 (r0483) or the abs olute value after the load gear (r2723) has exceeded the value range. 3: The maximum encoder value times the factor to convert the absolute position (r0483 and/or r2723) from increments to length units (LU) has exceeded the value range for displaying the position actual value. Remedy: If required, reduce the traversing range or position resolution (p2506). Increase the fine resolution of absolute position actual value (p0419). Reference to fault value = 3: If the value for the maximum possible absolute position (LU) is greater than 4294967296, an adjustment cannot be made due to an overflow. For rotary encoders, the maximu m possible absolute position (LU) is calculated as follows: 1. Motor encoder without position tracking: p2506 * p0433 * p2505 / (p0432 * p2504) p2506 * p0433 * p2505 * p0421 / (p0432 * p2504) for multiturn encoders 2. Motor encoder with position tracking for measuring gear p2506 * p0412 * p2505 / p2504 3. Motor encoder with position tracking for load gear: p2506 * p2721 * p0433 / p0432 4. Motor encoder with position tracking for load and measuring gear: p2506 * p2721 5. Direct encoder without position tracking: p2506 * p0433 / p0432 p2506 * p0433 * p0421 / p0432 for multiturn encoders 6. Direct encoder with position tracking for measuring gear: p2506 * p0412
