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 DBX1.5 /
1.6 (position measuring system 1/2)) in the axis-specific MD36300 $MA_ENC_FREQ_LIMIT [n] (n ... encoder number,
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 DBX1.5 / 1.6 (position measuring
system 1/2).
Program Restart part program.Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Continuation:
21611 [Channel %1: ] NC-controlled Extended Stop/Retract triggered
Parameters: %1 = Channel number
Definitions: "NC-controlled Extended Stop/Retract" triggered.
Reaction: 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 Clear alarm with the RESET key. 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 precisely determined.
1: The interface signal DB380x DBX2.1 (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
5: Drive signal DB390x DBX4000.4 (Autonomous drive) does not follow the NC setpoints
One of the motion-enabling signals (e.g. "Servo enable", "Pulse enable", parking/encoder selection (only for axes) or
drive-specific enables 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 following axis.
Reaction: The NC switches to follow-up mode.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
