Common Causes

• Z-axis (or ZB/XB/W-axis on sub-spindle/2-saddle models) not at the required positive end limit or workpiece chuting position when the catcher was commanded
• Door not closed when the parts catcher advance/retract command was issued
• Touch setter not at retract end when the catcher was commanded
• Main or sub spindle rotating while the catcher was advanced, or catcher not at retract end when spindle rotation was commanded
• Parts catcher limit switch failure detection: operation completed before the advance/retract timer expired (code 45)

Troubleshooting Steps

1. 1Read the code number shown with the alarm: code 0 = Advance commanded with Z-axis not at positive end limit, or axis move commanded with catcher advanced; code 1 = Advance commanded with the door not closed; code 2 = Advance/retract commanded with touch setter not at retract end; code 3 = Advance/retract commanded with the door not closed; code 4 = ZB-axis not at positive end limit, or ZB moved while catcher not at retract end; code 5 = Retract commanded while catcher not at swing-up end or while going down; code 6 = Swing up/down commanded while catcher not at advance end or while retracting; code 7 = Move to receive/retract position commanded while not at advance end or while going up
2. 2Read the code and satisfy the stated condition: Code 0 - move Z-axis to the positive end limit before advancing the catcher, and do not command axis moves while it is advanced; Code 1/3/25 - close the door first; Code 2/36/42 - retract the touch setter to its retract end.
3. 3Codes 4/21/22/23/26/27/30-35/40/41/43/44 - position the ZB, XB, W, Za, Zb or Zc axis within the permitted range (positive end limit, chuting position, or operation-enabled range) before commanding the catcher, and keep the catcher at retract end while those axes move.
4. 4Codes 5-11 - command the catcher motions in the correct sequence: swing up/down only at the advance end, retract only at the swing-up end, arm/guide moves only at the correct swing end positions.
5. 5Codes 13/15/24 - stop the main (or sub) spindle before advancing/retracting or raising/lowering the catcher, and never start spindle rotation while the catcher is advanced.
6. 6Codes 16/17/18 - confirm the shot work confirmation input is ON in automatic operation before door open/close or catcher rise commands; Code 45 - the catcher advance/retract finished before the operation timer, indicating a limit switch failure detection issue; inspect the catcher advance/retract limit switches and their wiring.
7. 7If it returns after these checks, record the alarm number, code and object and contact Okuma service.
