代码 SVGN-169: PushDepth%s[mm]clampd, speed affected
问题描述与安全警告
Fanuc R-30i Series Robot Controller 触发了严重的 PushDepth%s[mm]clampd, speed affected 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
Cause: The minimum push depth (internally calculated distance) required to decelerate from the contact speed exceeds the maximum possible pushing depth: part thickness + close stroke limit. The value of the minimum pushing depth (specified in the alarm message) was clamped to the maximum possible pushing depth. 4.ERROR CODES B-83124EN-6/02 Remedy: Decrease $sggun#.$setup.$push_margin, or increase the close stroke limit. Although this alarm has a warn severity, this condition should be corrected since the minimum push depth has been clamped to a value that is small enough to affect contact speed and/or contact speed persistence. Note 1: SVGN-169, basically indicates that the close limit value is abnormal, since minimum push depth is typically less than 5mm. Note 2: part thickness is automatically added to the pushing depth value during tryout mode to compensate for the missing part.
