Code 14162: [Channel %1: ] Block %2 error %3 on activation of the CUTMOD function
Issue Description & Safety Warning
The Siemens SINUMERIK 840D CNC has triggered a critical [Channel %1: ] Block %2 error %3 on activation of the CUTMOD function alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Parameters: %1 = Channel number %2 = Block number, label %3 = Error code Definitions: An error occurred during the activation of the CUTM OD function. The type of error is more closely defined by the error code number: Error code 1No valid cutting direction is defined for the active tool. 2The edge angles (clearance angle and holder angl e) of the active tool are both zero. 3The clearance angle of the active tool has an imper missible value (less than 0 degrees or greater than 180 degrees). 4The holder angle of the active tool has an impermi ssible value (less than 0 degrees or greater than 90 degrees). 5The cutting tip angle of the active tool has an impermissible value (less than 0 degrees or greater than 90 degrees). 6 The cutting edge position - holder angl e combination of the active tool is impermissible (with cutting edge positions 1 through 4, the holder angle mu st be less than or equal to 90 degrees, with cutting edge positions 5 through 8, it must greater than or equal to 90 degrees). 7 Impermissible rotation of the acti ve tool (the tool was rotated through +/-90 degrees (with a tolerance of about 1 degree) out of the active ma chining plane. As a result, the cutting edge position is no longer defined in the machining plane. With the aid of MD20125 $MC_CUTMOD_ERR, it can be determined for each of the named errors whether the fault condition is to lead to the issue of an alarm, and whether the alarm is only to be displayed or also trigger a program stop. Reaction: Interpreter stop Interface signals are set. Alarm display. Remedy: Correct the tool data of the active tool, or modify the part program in the case of error 7. Alternatively, suppress all error alarms with the aid of MD20125 $MC_CUTMOD_ERR. Diagnostics Manual (DAsl), 03/2009 Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
