Axis %2 Encoder %3 Frequency Exceeded; Axis %2: Enable Reset, Cause %3 - Siemens Sinamics S120 Diagnostic Manual

NCK alarms
Reaction: NC Start disable in this channel.
Alarm display.
Remedy: Remedy for error cause:
1 Define another travel direction
2 Deactivate the coupling and travel the axis/axes separately
3 Deactivate the coupling and travel the axis/axes separately
4 Reserved
5 Deactivate the transformation and travel the axis/axes separately
Program Clear alarm with the RESET key. Restart part program
Continuation:
21610 [Channel %1: ] Axis %2 encoder %3 frequency exceeded
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = String (encoder number)
Definitions: The maximum permissible frequency of the currently active encoder (axis-specific interface signal DB380x DBX0001.5
/ 1.6 (position measuring system 1/2)) in the axis-specific MD36300 $MA_ENC_FREQ_LIMIT [n] (n ... encoder num-
ber, 1 or 2) has been exceeded. The reference of the actual value to the mechanical slide position may have been lost.
The alarm can be reprogrammed in MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: Check MD36300 $MA_ENC_FREQ_LIMIT [n] and NC/PLC interface signal DB380x DBX0001.5 / 1.6 (position mea-
suring system 1/2).
Program Teileprogramm neu starten.Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Continuation:
21612 [Channel %1: ] Axis %2: enable reset, cause %3
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Cause of the alarm
Definitions: Causes of alarm:
0: The cause of the alarm cannot be preceisely determined.
1: The interface signal DB380x DBX0002.1 (Servo enable) is missing
2: The interface signal DB380x DBX4001.7 (Pulse enable) is missing
3: Drive signal DB390x DBX4001.7 (Impulses enabled) is not set
4: Drive signal DB390x DBX4001.5 (Drive ready) is not set
One of the motion-enabling signals (e.g. "Servo enable", "Pulse enable", parking/encoder selection (only for axes) or
drive-specific enables (such as terminal 663 with SIMODRIVE 611D) has been reset for the displayed axis. The alarm
can be reported with positioning axes, spindles and for axes from the geometry grouping.
The axes entered in the channel-specific MD array MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB are regarded
as axes belonging to the geometry grouping. Servo enable must exist for all available geometry axes, regardless of
whether or not they are currently in motion.
Occurs in connection with SAFETY function: If a test stop is performed with linked axes, the alarm is issued if a motion
command from the ELG grouping is pending during the test stop of the slave axis.
Reaction: The NC switches to follow-up mode.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
