Troubleshooting
•
DR-70-DP HANDSHAKE – Soft Fault
The 1395 Main Computer Board is no longer maintaining
communications with the Adapter through Dual-Ported
RAM. Ensure proper connection to Microbus interface.
Power down and then reapply power. If not solved, replace
Digital Reference Adapter. Reapply power; if not solved,
reinstall original Adapter, replace Main Control Board and
reapply power.
•
DR-71-Mbus RAM Test – Soft Fault
The 1395 Main Computer commanded an illegal mode for
this Adapter. Clear Fault, Power Down and reapply power. If
not solved, replace Digital Reference Adapter Board.
Reapply power; if not solved, reinstall original Adapter,
replace Main Control Board and reapply power.
•
DR-80-Low 24V Power Supply – Warning Fault
The 24 volt supply from the Console will be cycled in power
during normal operation which will cause the Drive to
regenerative stop. Once stopped the Drive will go back to the
Drive Ready State.
The Fault indicates that the remote 24 volt DC power supply
has failed. This can occur because of incorrect wiring of one
of the digital inputs from the paster or GSD console panel.
Check fuse on board, check voltage at terminal strip, etc.
Correct external problem, clear fault. If not solved, replace
Digital Reference Adapter.
•
DR-81-Logic State – Soft Fault
The internal Drive logic of the Digital Reference Adapter
Board has reached an invalid state. Clear fault, power down
and reapply power. If not solved, replace Digital Reference
Adapter Board.
•
DR-82-Auxiliary Logic – Soft Fault
The auxiliary input logic via digital inputs 9 and 10 cannot be
set to the same bit (ie. Parameters 578 and 579 must not be
set equal to each other if they are set to anything other than
16). The auxiliary inputs are a way to run and stop the Drive
without using the internal logic state diagram based logic
system. Correct Parameters, clear fault. If not solved, replace
Digital Reference Adapter Board.
