490 System Memory Allocation Error
Cause:
The dynamic memory space on the control has been exhausted. This
diagnostic message is related to the amount of memory consumed by the
compiled program as well as operations being performed dynamically,
such as index CAM builds. The amounts of configured memory in the
sizing icon directly effect the amount of system memory available.
Remedy:
1. The amount of memory available in the system can be viewed under
menu selection Diagnostics ⇒
⇒⇒
⇒ System. One way to decrease
memory usage would be to verify that all the items being selected
within the sizing icon are necessary.
2. Example: If only 3 event functions are used in the current
VisualMotion program but 10 events are reserved in memory within
the sizing icon, then the addition 7 events use up unnecessary
memory resources. Decrease each field within the sizing icon to free
up memory space.
3. If the problem persists, contact Bosch Rexroth Service for assistance.
492 Programs were lost, see ext. diag.
Cause:
User programs and data have been erased from the control’s memory.
This can be due to a new firmware version or a size change in the
number of parameters in the system. In addition to these reasons,
commanding a C-0-0996 (Clear Programs and Data Memory) can also
generate a 492 error.
Note: If the control’s memory was cleared by using C-0-0996, the
diagnostic log will contain the warning message 211 Programs
and Memory Cleared.
Refer to the extended diagnostic message C-0-0124 for an explanation.
Extended diagnostics and diagnostic log can be viewed by selecting
Diagnostics ⇒
⇒⇒
⇒ System in VisualMotion Toolkit. The following extended
diagnostic messages are possible:
Extended Diagnostic C-0-0124 Description
Firmware Version String Changed A new GPP or GMP firmware version was
copied to the control’s memory card.
Parameter Table Size Changed A different parameter table size was
detected from the last time the control was
power up.
