代码 21612: [Channel %1: ] Axis %2: enable reset, cause %3
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 [Channel %1: ] Axis %2: enable reset, cause %3 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
Parameters: %1 = Channel number %2 = Axis name, spindle number %3 = Cause of the alarm Definitions: Causes of alarm: 0: The cause of the alar m cannot be preceisely determined. 1: The interface signal DB31,... DBX2.1 (Servo enable) is missing 2: The interface signal DB31,... DBX21.7 (Pulse enable) is missing 3: Drive signal DB31,... DBX93. 7 (Impulses enabled) is not set 4: Drive signal DB31,... DBX93.5 (Drive ready) is not set One of the motion-enabling signals (e.g. "Servo enable", "Pulse enable", parking/encoder selection (only for axes) or drive-specific enables (such as terminal 663 with SIMODRIVE 611D) has been reset for the displayed axis. The alarm can be reported wi th positioning axes, spindles and for axes from the geometry grouping. The axes entered in the channel-specific MD array MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB are regarded as ax es belonging to the geometry grouping. Servo enable must exist for all av ailable geometry axes, regardless of whether or not they are currently in motion. Occurs in connection with SAFETY function: If a te st stop is performed with linked axes, the alarm is issued if a motion command from the ELG grouping is pending during the test stop of the slave axis. Reaction: The NC switches to follow-up mode. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Diagnostics Manual (DAsl), 03/2009 Remedy: Please inform the authorized personnel/service department. Check the interface signals DB31,... DBX2.1 (S ervo enable), DB31,... DBX21.7 (Pulse enable), check the drive signals DB31,... DBX93.7 (Pulse s enabled), DB31,... DBX93.5 (Drive ready) for example with the PLC status display in the DI AGNOSTICS operating area. Check the encoder selection (for axes) as well as ot her signals enabling motion (such as SIMODRIVE 611D terminal 663 etc.) according to the drive type used. When the terminal enables of the drive have failed, trace back the wiring or hardware function (for example relay function) or proceed as st ated in the relevant drive documentation. With SAFETY: With active actual-value linkage, out put of the error message on the slave axis can be prevented by increasing MD36060 $MA_STAN DSTILL_VELO_TOL (default value is 5 mm). Program Continuation: Clear alarm with the Delete key or NC START.
