Been talking to Dwayne at KC Robotics about trying to get the drives powered up. Got email instructions from him (actually from KC’s Kuka guy) as follows:

Navigate to C:KRC\Roboter\Init
Open file IOSYS.INI
It will look something like this:

;==========================================================
; IOSYS.INI - Configuration file for the IO-System
;==========================================================

; For configuration help go to the end of this file.

;----------------------------------------------------------

; ATTENTION !!!! Since V5.0 Build13 we have removed the DeviceNet
;                driver "dndrv.o". Now you have to use the driver
;                "dn2drv.o" and the appropriate syntax (form 2)

[CONFIG]
VERSION=2.00

[DRIVERS]
;CNKE2=21,cnke2CPInit,cnke2drv.o
;DNSC6=20,dnsc6Init,dnsc6drv.o
;DNSC5=19,dnsc5Init,dnsc5drv.o
;DNSC4=18,dnsc4Init,dnsc4drv.o
;DNSC3=17,dnsc3Init,dnsc3drv.o
;CNKE1=16,cnke1CPInit,cnke1drv.o
;INTERBUSPCI=15,ibsCPPciInit,ibpcidrv.o
;DSEIO=14,dseIoInit,dseiodrv.o
;DNSC2=13,dnsc2Init,dnsc2drv.o
;DNSC1=12,dnsc1Init,dnsc1drv.o
;PBMASL=11,pbmsInit,pfbmsdrv.o
DEVNET=2,dnInit,dn2drv.o
;INTERBUS=1,ibusInit,ibusdrv.o
;MFC=0,mfcEntry,mfcdrv.o

To disable the LPDN driver.  Make sure there is a semi-colon before each DNSC line.

Leaned later that I was supposed to do this through Windows Explorer, but managed to open IOSYS.INI through the controller interface (Configure -> I/O Driver -> Edit Config.). It didn’t quite look like the above, but it did have a few DNSC lines that weren’t commented out.

Restarted the controller and now there is only one message left:
200 Drives contactor off.

That’s progress, but still can’t jog it.
