Overview of Alarms
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - 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: Modify MD 36300: ENC_FREQ_LIMIT [n] and interface signal position measuring system
1/2 (DB 31 - 48, DBX 1.5 and DBX 1.6).
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
21611
Channel %1 NC-controlled Extended Stop/Retract triggered
Parameters: %1 = Channel number
Definitions: "NC-controlled Extended Stop/Retract" triggered.
Reactions: - 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.
- All channel-specific alarm reactions are delayed with this alarm, alarm display.
Remedy: Reset
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:

Channel %1 axis %2: 'Servo enable' reset during motion.
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The interface signal "Servo enable" (DB31 - 48, DBX 2.1),
the interface signal "Pulse enable" (DB31 - 48, DBX 21.7)
or other signals enabling the motion such as
parking/encoder selection (only for axes) or drive-specific
enables such as terminal 663 etc. (for example in SIMODRIVE 611D)
have been set to 0 for the displayed axis even though one of the axes in the geometry
grouping was in motion.
The axes entered in the channel-specific MD array 20050
AXCONF_GEOAX_ASSIGN_TAB count as axes belonging to the geometry grouping.
Servo enable must exist for all available geometry axes, regardless of whether they are
currently in motion or not.
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 ELT grouping is pending during the test
stop of the slave axis.
Reactions: - The NC switches to follow-up mode.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department.
