Block %3 Axis %2 Touch Probe Deflected, Edge Polarity Not Possible; Block %3 Axis %2 Measurement Not Possible - Siemens Sinamics S120 Diagnostic Manual

21700 [Channel %1: ] Block %3 axis %2 touch probe already deflected, edge polarity not
possible
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Definitions: The probe programmed under the keyword MEAS or MEAW is already deflected and has switched. For a further mea-
suring operation, the probe signal must first be canceled (quiescent state of the probe).
The axis display is of no significance at the present time but an axis-specific evaluation has been planned for later
stages of development.
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Verify the starting position of the measuring operation or check the probe signals in the PLC interface DB2700
DBX0001.0 / .1 (Probe actuated key 1/key 2). Are the cables and connectors in good order?
Program Clear alarm with the RESET key. Restart part program
Continuation:
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).
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Correct the measurement tasks.
Program Clear alarm with the RESET key. Restart part program
