Extended Diagnostic C-0-0124 Description
Virtual Master %d Max. Vel. Exceeds
%.f RPM
%d = Virtual Master number 1 or 2
%.f = Max. ELS velocity less 1 RPM
Table 3-20: ELS Config. Error Extended Diagnostic
Remedy:
To correct the problem, the Virtual Master’s maximum velocity program
variable VM#_MAX_VEL (where # = Virtual Master number) must be set
to a value that does not exceed the calculated Max ELS Velocity Limit
less 1 RPM.
568 Axis %d: Assigned Task is Not Defined
Cause:
This error is issued when an axis (or axes) is assigned to a user task that
has not be defined in a single axis application. Axis assignments are
made in the Axis icon of the Initialization task.
Remedy:
Modify the Axis icon and change the assigned task to one that exists.
570 ELS Max. Vel. Exceeded, see ext. diag.
Due to the nature of rotary motion, the proper operation of ELS is limited
to velocities less than 180° per SERCOS cycle. Therefore, both the
generation and processing of motion in ELS are being limited to velocities
less than 180° per SERCOS cycle.
The maximum ELS velocity limit is calculated as a function of the current
SERCOS cycle time.
SERCOS
Cycle Time
Max. ELS Velocity Limit
(180° / SERCOS Cycle)
Max. ELS Velocity Limit
Less 1 RPM
2 ms 15,000 RPM 14,999 RPM
4 ms 7,500 RPM 7,499 RPM
8 ms 3,750 RPM 3,749 RPM
16 ms 1,875 RPM 1,874 RPM
Table 3-21: Maximum ELS Velocities
Cause:
The maximum ELS velocity for the current SERCOS cycle time has been
exceeded. This error is issued with an extended diagnostic.
