Bad IO just means it can't see something on it's IO side. In this case the second device defined in the Ethernet IP menu. This shouldn't keep you from jogging though.

See what alarms you have active in the alarm menu (menu->4).

Next you would probably need to disable UOPS (menu->next->config), and make sure all the safety circuits are complete.
Check out the position converter I wrote here!

errors srvo-223 and srvo-058 comes up and the red led SVEMG led on the board is lit right from the start...

srvo-223 is a symptom of srvo-058. Here's the troubleshooting steps for the srvo-058:

SRVO–058 FSSB init error (Group : i Axis : j)
Communication  was  interrupted  between  the  main
board and servo amplifier.
(Action 1)
Check whether fuse F3 in the power supply unit has
(Action 2)
Turn   off   the   power   and   disconnect   the   CRF7
connector on the servo amplifier.  Then turn on the
power  and  check  whether  this  alarm  occurs  again.
(Ignore     the     alarm     SRVO–068     because     of
disconnecting  the  CRF7  connector.)    If  this  alarm
does not occur, the RP1 cable of the robot connection
cable  or  the  internal  cable  of  the  robot  may  be
short–circuited to the ground.  Check the cables and
replace it if necessary.
(Action 3)
Check whether the LED (P5V and P3.3V) on the servo
amplifier is lit.  If they are not lit, the DC power is not
supplied   to   the   servo   amplifier.      Make   sure   the
connector CP6 and CRM67 on the E–stop unit and the
connector CRM67 on the servo amplifier are connected
tightly.  If they are connected tightly, replace the servo
(Action 4)
Check   the   communication   cable   (optical   fiber)
between the main board and servo amplifier.  Replace
it if it is faulty.
(Action 5)
Replace the axis control card on the main board.
(Action 6)
Replace the servo amplifier.
(Action 7)
If the other units (the servo amplifier for the auxiliary
axis and the line tracking interface) are connected in
the  FSSB  optical  communication,  disconnect  these
units and connect only the 6–channel servo amplifier
for the robot.  Then turn on the power.  If this alarm
does not occur, search the failed unit and replace it.
Before  continuing  to  the  next  step,  perform  a  complete  controller
back–up to save all your programs and settings.  Failure to perform
this could result in damage to equipment or lost data.
(Action 8)
Replace the main board.

thanks for replyin.....

-the fuses FS1,FS2,FS3, FUSE1,FUSE2, works right......
 -there Is port CFR8 instead of CFR7 and when i start the robot controller after disconnecting it , no alarm pops up; it still says just SRVO 223 and SRVO058
 -the SVEMG led is lit red always even if i push/release the e-stop on the controller
 -the OPEN led led is not lit at all anytime
 -the ALARM led is not lit at all, eventhough it shows thers alarm showin on the TP
 -i pulled out the optical fibre comm cable and restarted ; still says the same error

 :help: :help: :help:
