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 preceisely determined.
1: The interface signal "Servo enable" (DB31 - 61, DBX 2.1) is missing
2: The interface signal "Pulse enable" (DB31 - 61, DBX 21.7) is missing
3: Drive signal "Enable pulse" (DB31 - 61, DBX 93.7) is not set
4: Drive signal "Drive Ready" (DB31 - 61, DBX 93.5) 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 (SIMODRIVE 611D), has been reset for
the displayed axis. The alarm can be reported with positioning axes, spindles and for axes in the
geometry grouping.
The axes entered in the channel-specific MD array 20050 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.
Remedy: Please inform the authorized personnel/service department.
Check the interface signals "Servo enable" (DB31 - 61, DBX 2.1) and "Pulse enable" (DB31 - 61, DBX
21.7), check the drive signals "Pulse enabled" (DB31 - 61, DBX 93.7), "Drive Ready" (DB31 - 61, DBX
93.5) for example with the PLC status display in the DIAGNOSTICS operating area. Check the
encoder selection (for axes) as well as other signals enabling motion such as terminal 663 depending
on the drive type used, and so on.
When the terminal enables of the drive have failed, trace back the wiring or hardware function (for
example relay function) or proceed as stated in the relevant drive documentation.
With SAFETY: With active actual-value linkage, output of the error message on the slave axis can be
prevented by increasing MD 36060 $MA_STANDSTILL_VELO_TOL (default value is 5 mm).
Program Clear alarm with the Delete key or NC START.
