代码 231-8320: PIC: Actual value does not equal the nominal value %1
问题描述与安全警告
Heidenhain TNC Series CNC 触发了严重的 PIC: Actual value does not equal the nominal value %1 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 of error] Possible cause: The measurement range of current of the inverter is not set to the range specified in the configuration. This message can appear, for example, if a new CC controller unit has been installed or there was an unexpected change to the configuration. "PIC" designates a microcontroller inside the inverter that switches and reads back the measurement range of current. - Nominal value (value in column S of the power module table) = 1, however: - There is no PIC - PIC can't be switched - Access to PIC is deactivated (machine parameter motEncCheckOff, Bit16=1) - Nominal value (value in column S of the power module table) = 0, however: - Access to PIC is deactivated (machine parameter motEncCheckOff, Bit16=1) and PIC was already switched to 1 [Error correction] - Check the power module entered in the machine configuration - Check the nominal value of the PIC (value in column S of the power module table) - Perhaps change the PWM frequency (to >= 5 kHz) - Perhaps exchange the power module
