39520, Communication lost with Drive Module
Description
The main computer has lost contact with drive module arg.
Consequences
The system goes to status SYS HALT No operation will be
possible until the fault has been corrected.
Probable causes
This may be due to a cable break, badly connected connector
or high levels of interference in the cable.
Recommended actions
Make sure the cable between control module and drive module
is not damaged and that both connectors are correctly
connected. Make sure no extreme levels of electromagnetic
interference are emitted close to the robot cabling.
39521, Drive Module Communication Warning
Description
There are a large number of communication errors being
detected on the Ethernet link to drive module arg.
This can be due to external noise sources interfering with the
cable.
Recommended actions
Check that there are no electromagnetic interference sources
running near the cable or the drive or computer modules.
39522, Axis computer not found
Description
The axis computer in drive module arg is not connected to the
main computer.
Consequences
The system goes to system failure state. No operation will be
possible until the fault has been corrected.
Probable causes
This may be due to a cable break, badly connected connectors,
or loss of power supply.
Recommended actions
Make sure that the cable between the main computer and the
axis computer is not damaged and that both connectors are
correctly connected. Make sure that the power supply to the

Description
The system has failed to complete the initialization phase of
drive module arg .
Consequences
The system goes to system failure state.
Probable causes
The system has failed to complete the initialization phase of
the drive module.
Recommended actions
Retry by restarting the controller using the main power switch.
Check for other hardware event log messages.
39526, Axis computer not found in Multi Move
