代码 207594: <location>Encoder 2: Value range for position actual value exceeded

问题描述与安全警告

Siemens SINUMERIK 840D CNC 触发了严重的 <location>Encoder 2: Value range for position actual value exceeded 警报。需要由合格的操作员或维修技师立即处理,以防止在制造周期中对设备造成二次损坏或导致零件报废。在接触电气控制箱之前,请务必确保遵循标准安全和停机挂牌 (LOTO) 程序。

官方故障排除步骤

Message value: %1 Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE 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. Re alarm value = 3: Reducing the position resolution and conversion factor: - reduce the length unit (LU) per l oad revolution for rotary encoders (p2506). - increase the fine resolution of absolute position actual values (p0419).
