Robot loses
taught stations
after power-on
cycle
After power-on
cycle, robot
does not move
to previously
taught stations
NVSRAM
failure
Bit 13 Try to reformat
NVSRAM. If successful,
re-download PAR and
Macro files, and then re-
teach stations.
Otherwise, try with new
NVSRAM. Ensure
correct jumper setup.
Robot moves
erratically
Robot performs
normally but an

Bad Encoder Perform Encoder test
(Diagnostics Step 3).
Replace Encoder if
required.
Bad amplifier
module
(especially after
Controller box
passes warm-up
period)
Bits 4
and 10
Perform Encoder test
(Diagnostics step #3) to
make sure it is NOT an
Encoder problem. If the
Encoder is OK, replace
the amplifier module.
Excessive noise
to Galil board or
bad Galil board
Bit 14 Send Galil command.
You must receive “.”
Response. Press Enter
several times. If you
receive “>“ response,
replace Galil board. If
problem persists, re-
route grounding and
proper shielding.
Interrupted
Encoder signal
Replace flex-PCB.
