The Pacific Scientific PC833 and PC834 servo drives must be offset-nulled when installed in your equipment. Refer to your machine documentation for this procedure.

The Pacific Scientific PC833 and PC834 servo drives are repaired and tested at our facility. Once they are returned and installed in your equipment, they must be offset-nulled.

If you install without offset-nulling, the drive will zero and jog manually but the machine will fault when started. The drive's green LED should be lit steady and red fault LED should be out. If you do not offset-null the amplifier, the drive will zero properly but once you press start the green LED will flash and the computer system will report a drive fault on screen.
