Axis %2 Master-Slave Not Configured; Axis %1 Parameter Set Change From %2 To %3 Not Possible; In Block %2 Unanticipated Stop Crossed In Continuous Path Mode - Siemens Sinamics S120 Diagnostic Manual

26032 [Channel %1: ] Axis %2 master-slave not configured
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The master-slave coupling could not be activated because of incomplete configuration.
Reaction: 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 Clear alarm with the RESET key. Restart part program

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 content of the parameter block to
be switched on, e.g. different load gear factors.
Reaction: 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 the following cases, the parameter block change is carried out via MD31060 $MA_DRIVE_AX_RATIO_NUMERA
and MD31050 $MA_DRIVE_AX_RATIO_DENOM without an alarm, even with different load gear ratio settings:
1. If no position control is active (e.g. in follow-up mode or if spindle is in speed-controlled mode).
2. For position control with the direct encoder.
3. For position control with the indirect encoder (the calculated load position difference must not exceed the value indi-
cated in MD36500 $MA_ENC_CHANGE_TOL).
Program Clear alarm with the RESET key. Restart part program
Continuation:
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 decelerate 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 MD35500
$MA_SPIND_ON_SPEED_AT_IPO_START > 0, and the machine has to wait until the spindle has returned to the set-
point range. Another possible cause is that a synchronized action needs to be finished before the path interpolation
continues. The alarm is only output if MD11400 $MN_TRACE_SELECT = 'H400'. The alarm output is normally sup-
pressed. - MD11400 $MN_TRACE_SELECT has SIEMENS password protection.
Reaction: Alarm display.
Remedy: MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START = 1. Program G09 before the alarm output in the block to allow
the path interpolation to stop as planned.
Program Clear alarm with the Delete key or NC START.
