Program Continuation:
Channel %1 axis %2: 'Servo enable' reset during motion.
%1 = Channel number
%2 = Axis name, spindle number
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.
- The NC switches to follow-up mode.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Please inform the authorized personnel/service department.
Check the interface signals "Servo enable" (DB31 - 48, DBX 2.1) and "Pulse enable" (DB31 - 48, DBX 21.7), 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 per 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).
Clear alarm with the Delete key or NC START.
