Axis %2 $Aa_Esr_Enable = 1 But Axis Should Be Set To Neutral; Axis %2 Is Neutral And $Aa_Esr_Enable = 1 Should Be Set; Axis %2, $Aa_Esr_Enable = 1, Axis Exchange Not Executed In This State - Siemens Sinamics S120 Diagnostic Manual

NCK alarms
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Possible causes:
- MD 30240 $MA_ENC_TYPE not equal to 0 as a result of an oversight; the encoder should actually be simulated (= 0).
- MD 30220 $MA_ENC_MODULE_NR entered incorrectly, i.e. the logical drive numbers were transposed and an
invalid value is stored for this drive in MD 13050 $MN_DRIVE_LOGIC_ADDRESS (see next paragraph), or a drive
number which does not exist on the bus was entered (check the number for slaves, for example).
- MD 13050 $MN_DRIVE_LOGIC_ADDRESS contains values which were not configured on the Profibus (i.e. the val-
ues are not in SDB Type 2000) or different addresses were selected for the input and output slots of the drive in the
Profibus configuration.
- A fatal encoder error was detected during the selection of the encoder (encoder defective, removed), so that park
status cannot be left (in such a case, this alarm is triggered instead of alarm 25000/25001 - please refer to them for
other possible causes of the error).
Program Switch control OFF - ON.
Continuation:
26120 [Channel %1: ] Axis %2 $AA_ESR_ENABLE = 1 but axis should be set to NEUTRAL
Parameters: %1 = Channel
%2 = Axis, spindle
Definitions: One axis with ESR configuration and $AA_ESR_ENABLE[Achse] = 1 should be set to NEUTRAL.
However, neutral axes (apart from single axes) cannot execute an ESR.
Reaction: Alarm display.
Remedy: Set $AA_ESR_ENABLE[Achse] = 0 before setting axis to NEUTRAL.
Alarm can be suppressed via MD11415 $MN_SUPPRESS_ALARM_MASK_2 bit 6 = 1.
Program Clear alarm with the Delete key or NC START.
Continuation:
26121 [Channel %1: ] Axis %2 is NEUTRAL and $AA_ESR_ENABLE = 1 should be set
Parameters: %1 = Channel
%2 = Axis, spindle
Definitions: $AA_ESR_ENABLE[Achse] = 1 should not be set to neutral axes (apart from single axes).
Neutral axes (apart from single axes) cannot execute an ESR.
Reaction: Alarm display.
Remedy: Do not apply $AA_ESR_ENABLE[Achse] = 1 to neutral axes (apart from single axes).
Alarm can be suppressed via MD11415 $MN_SUPPRESS_ALARM_MASK_2 bit 6 = 1.
Program Clear alarm with the Delete key or NC START.
Continuation:
26122 [Channel %1: ] Axis %2, $AA_ESR_ENABLE = 1, axis exchange not executed in this
state
Parameters: %1 = Channel
%2 = Axis, spindle
Definitions: With $AA_ESR_ENABLE[Achse] = 1 axis exchange not permitted.
