Sinumerik Alarm 21701 Channel %1 block %3 axis %2 measurement not possible
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Definitions:
Measurement level 2 (MEASA, MEAWA, MEAC). There is an error in the programmed measurement task.
Possible causes:
• Invalid measurement mode
• Invalid probe
• Invalid encoder
• Invalid number of measurement signal edges
• Identical measurement signal edges are only programmable in mode 2
• Invalid FIFO number
• Mismatch between the number of FIFOs programmed and the number of probes used in the measurement task.
Further causes:
• A measurement task is already active (e.g. from a synchronized action).
Reactions:
– Alarm display.
– Interface signals are set.
– Local alarm reaction.
– NC Stop on alarm.
– NC Start disable in this channel.
– If the axis is a single axis when this alarm is triggered, the alarm is only effective for this axis (not effective for e.g. the channel or mode group)
Remedy:
Correct the measurement tasks.
Program Continuation:
Clear alarm with the RESET key. Restart part program
