26052 [Channel %1: ] In block %2: path velocity too high for auxiliary function output
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: This alarm usually occurs in a block with auxiliary function output during a movement. In this case, the wait for acknowl-
edgement 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). On the next
block change, the path continues unless the abrupt stop has caused an error in the position controller (e.g. because
MD36400 $MA_CONTOUR_TOL setting was over-sensitive).
Reaction: Alarm display.
Remedy: - If the alarm occurred in a block with auxiliary function output during the movement: from SW 5.1 or higher, increase
machine MD10110 $MN_PLC_CYCLE_TIME_AVERAGE or
- Program G09 in the block indicated in the message to allow the path interpolation to stop as planned.
Program Clear alarm with the Delete key or NC START.

26053 [Channel %1: ] Block %2 interpolation problem in Look Ahead (module %3, identifier
%4)
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Module identifier
%4 = Error code
Definitions: Synchronism between interpolation and preparation is faulty.
Reaction: Interpreter stop
Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please contact Siemens.
Program Clear alarm with the RESET key. Restart part program
Continuation:
26054 [Channel %1: ] Block %2 interpolation warning in Look Ahead (module %3, problem
%4)
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Module identifier
%4 = Error code
Definitions: The computer performance is inadequate to create a smooth path velocity profile. This can lead to drops in velocity.
Reaction: Local alarm reaction.
Alarm display.
Warning display.
Remedy: Change parameterization. Increase interpolation cycle.
Program Clear alarm with the Delete key or NC START.
