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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
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
DB31, ... 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 (chan-
nel 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 DB31, ... DBX1.5 / 1.6
(position measuring system 1/2).
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
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 DB31, ... DBX2.1 (Servo enable) is missing
2: The interface signal DB31, ... DBX21.7 (Pulse enable) is missing
3: Drive signal DB31, ... DBX93.7 (Impulses enabled) is not set
4: Drive signal DB31, ... DBX93.5 (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 cur-
rently 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.
