[Channel %1: ] In block %2 unanticipated stop crossed in continuous path mode
Parameters:
%1 = Channel number
%2 = Block number, label
Explanation:
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 setpoint
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 suppressed. - 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.
Programm
continuation:
Clear alarm with the Delete key or NC START.

[Channel %1: ] In block %2: path velocity too high for auxiliary function output
Parameters:
%1 = Channel number
%2 = Block number, label
Explanation:
This alarm usually occurs in a block with auxiliary function output during a movement. In this case, the wait for
acknowledgement of the auxiliary function was longer than planned.
The alarm also occurs if internal control inconsistencies cause continuous path mode (G64, G641, ...) to be blocked
unexpectedly.
The path interpolation stops abruptly at the end of the block indicated in the message (regenerative stop). Alarm 21620 is
often triggered as a follow-up alarm. If not, the path continues after the block change.
Reaction:
Alarm display.
Remedy:
- The time calculated for the auxiliary function output during the movement comes from the PLC in most systems. Otherwise,
MD10110 $MN_PLC_CYCLE_TIME_AVERAGE is used for this purpose.
- The alarm can basically be avoided by programming in the block G09 indicated in the message. This stops the path
interpolation briefly at the end of the block.
Programm
continuation:
Clear alarm with the Delete key or NC START.

Remedy:
Please contact Siemens.
Programm
continuation:
Clear alarm with the RESET key. Restart part program
