Overview of Alarms
NCK alarms
Program Con- Switch control OFF - ON.
tinuation:
26120 [Channel %1: ] Axis %2 $AA_ESR_ENABLE = 1 but axis should be set to
NEUTRAL
Parameters: %1 = Channel
%2 = Axis, spindle
Definitions: One axis with ESR configuration and $AA_ESR_ENABLE[Achse] = 1 should be set to NEUTRAL.
However, neutral axes (apart from single axes) cannot execute an ESR.
Reaction: Alarm display.
Remedy: Set $AA_ESR_ENABLE[Achse] = 0 before setting axis to NEUTRAL.
Alarm can be suppressed via MD11415 $MN_SUPPRESS_ALARM_MASK_2 bit 6 = 1.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
26121 [Channel %1: ] Axis %2 is NEUTRAL and $AA_ESR_ENABLE = 1 should
be set
Parameters: %1 = Channel
%2 = Axis, spindle
Definitions: $AA_ESR_ENABLE[Achse] = 1 should not be set to neutral axes (apart from single axes).
Neutral axes (apart from single axes) cannot execute an ESR.
Reaction: Alarm display.
Remedy: Do not apply $AA_ESR_ENABLE[Achse] = 1 to neutral axes (apart from single axes).
Alarm can be suppressed via MD11415 $MN_SUPPRESS_ALARM_MASK_2 bit 6 = 1.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
26122 [Channel %1: ] Axis %2, $AA_ESR_ENABLE = 1, axis exchange not
executed in this state
Parameters: %1 = Channel
%2 = Axis, spindle
Definitions: With $AA_ESR_ENABLE[Achse] = 1 axis exchange not permitted.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Set $AA_ESR_ENABLE[axis] = 0 before axis exchange.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation: Set $AA_ESR_ENABLE[axis] = 0
26123 [Channel %1: ] Axis %2, $AA_ESR_ENABLE = 1 should be set, but
MD37500 $MA_ESR_REACTION = 0
Parameters: %1 = Channel
%2 = Axis, spindle
Definitions: $AA_ESR_ENABLE[axis] = 1 should only be set on axes with MD37500
$MA_ESR_REACTION[Achse] > 0.
The following example brings about the alarm:
N100 $MA_ESR_REACTION[AX1] = 21
N110 $AA_ESR_ENABLE[AX1] = 1
N120 NEWCONF
because MD37500 $MA_ESR_REACTION[AX1] = 21 will become known to the NCK at the time of
N120 NEWCONF.
Correct would be:
N100 $MA_ESR_REACTION[AX1] = 21
N110 NEWCONF
N120 $AA_ESR_ENABLE[AX1] = 1
Reaction: Alarm display.
