What the NoDriveCfg alarm means

The CS8 reports 'Internal error DRIVE NoDriveConfiguration' for every axis and refuses arm power ('arm power enable request refused: cabinet working mode is remote or invalid') — the controller cannot identify the arm at all. This is one of the faults our repair team handles on Staubli CS8 / CS9 (VAL3) systems — the cause is usually identifiable within the first on-site inspection.

Most common causes

  • Corrupt or missing arm.cfx configuration file in usr/configs
  • Missing or corrupt system.zfx in the sys partition
  • Failed restore after a CF card change
  • Controller/arm pairing lost
Field note: the first item on this list is what we find most often on real machines. Check it before you go deeper.

Step-by-step field fix

  1. Connect to the controller filesystem via FTP
  2. Upload a correct arm.cfx (from the original CD or backup) into usr/configuration
  3. Verify the arm.cfx header contains the correct order number and arm type
  4. Restart the CS8 — the drive errors should disappear and the hand symbol follow the WMS mode selector
  5. If system.zfx is corrupted, contact Staubli support for the matching system file
Safety first: never bypass safety circuits or force contactors closed. If the alarm involves E-stop chains, brakes or drive power, and you are not a trained robot technician, contact a professional — wrong moves here can cost you a robot or an injury.
