代碼 10720: [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 path programmed for the axis violates the currently valid software limit switch. The alarm is activated when preparing the part program block. If bit 11=0 in the machine data MD11411 $MN_ENABLE_ALARM_MASK, this alarm is issued instead of alarm 10722. If bit 11 is set in the machine data MD11411 $MN_ENABLE_ALARM_MASK, an expanded diagnostics option is offered for the software limit switch violation. The condition for activation is the presence of the ALUN* alarm file in the HMI. Reaction: Correction block is reorganized. Local alarm reaction. Interface signals are set. Alarm display. Remedy: Check and correct positions in the NC program. Please inform the authorized personnel/service department. Check machine data: MD36100 $MA_POS_LIMIT_MINUS / MD36120 $MA_POS_LIMIT_MINUS2 and MD36110 $MA_POS_LIMIT_PLUS / MD36130 $MA_POS_LIMIT_PLUS2 for the software limit switches. Check the axis-specific interface signals: DB31,... DBX12.3 / 12.2 (2nd software limit switch plus/minus) to see whether the 2nd software limit switch is selected. Check the currently active work offsets via the current frame. Work offsets, overlaid movements ($AA_OFF), DRF and transformation components must also be checked. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
