Código 10721: [Channel %1: ] Block %3 axis %2 software limit switch %4

Parameters: %1 = Channel number %2 = Axis name, spindle number %3 = Block number, label %4 = String ( + or - ) Definitions: The motion planned for the axis violates t he currently valid software limit switch. The alarm is activated during the preproce ssing of approach or rest blocks for REPOS. Depending on MD11411 $MN_ENABLE_ALARM_MASK, bit11=0 this alarm is output instead of alarm 10723. If this MD11411 $MN_ENABLE_ALARM_MASK, bit11 is set in this machine data $MN_ENABLE_ALARM_MASK, an expanded diagnostics opt ion is offered for the software limit switch violation. The condition for activation is the presence of the ALUN* alarm file in the HMI. See also the Diagnostics Manual for alarm 10723. Reaction: Local alarm reaction. Interface signals are set. Alarm display. Remedy: Determine the cause of the offset from the initial or target position. The REPOS command is executed at the end of an ASUB or system ASUB. See also cross reference from ASUBs. Check the axis-specific NC/PLC interface signals DB 31,... DBX12.3 / 12.2 (2nd software limit switch plus/minus) to see whether the 2nd software limit switch is selected. Check the currently active work offset via the current frame. Also check the external work offsets, overlaid movements ($AA_OFF), DRF and transformation components. Cancel the NC program with NC reset. Program Continuation: Clear alarm with the RESET key. Restart part program
