Overview of Alarms
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26032
Axis %1 master-slave not configured
Parameters: %1 = Axis name, spindle number
Definitions: The master-slave coupling could not be activated because of incomplete configuration.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Check the current configuration of the master-slave coupling.
The configuration can be modified via the MASLDEF instruction or the machine data
MD37250 $MA_MS_ASSIGN_MASTER_SPEED_CMD and MD37252
$MA_MS_ASSIGN_MASTER_TORQUE_CTR.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26050
Axis %1 parameter set change from %2 to %3 not possible
Parameters: %1 = Axis name, spindle number
%2 = Index: current parameter block
%3 = Index: new parameter block
Definitions: The parameter block change cannot be performed without jumps. This is due to the con-
tent of the parameter block to be switched on, e.g. different load gear factors.
Reactions: - The NC switches to follow-up mode.
- Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: In following cases, the parameter block change is carried out via MD 31060 and MD
31050 without an alarm, even with different load gear ratio settings:
1. In speed-controlled and follow-up mode.
2. With position control with the direct encoder.
3. With position control with the indirect encoder only within the position window (MD
36500 > actual position > MD 36500).
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
26051
Channel %1 in block %2 unanticipated stop crossed in continuous path mode
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The path interpolation did not stop, as required, at the end of the block, but will only decel-
erate to a standstill in the next block. This error situation occurs if the stop at block change
was not planned by the path interpolation or was not detected early enough. A possible
cause is that the PLC changed the spindle speed when
$MA_SPIND_ON_SPEED_AT_IPO_START > 0, and the machine has to wait until the
spindle has returned to the setpoint range. Another possible cause is that a synchronized
action needs to be finished before the path interpolation continues. The alarm is only out-
put if $MN_TRACE_SELECT = 'H400'. The alarm output is normally suppressed. -
$MN_TRACE_SELECT has SIEMENS password protection.
Reactions: - Alarm display.
