A Daewoo machine identified as an ACE-V500s in the reported title and as an ACE-500s in the machine description is consuming approximately two way-lube tanks per day. Most of the lubricant reaches the coolant tank or floor. The machine uses a Fanuc 18i-MB control, but the available evidence does not identify a verified parameter, timer address, or adjustment value.
Confirm the Machine and Failure Mode
Resolve the ACE-V500s versus ACE-500s model discrepancy from the machine nameplate before requesting documentation. Also observe the lubrication system during operation to distinguish excessive commanded pumping from a leaking, disconnected, or misdirected lubrication path. Lubricant reaching the floor does not, by itself, prove that pump timing is incorrect.
| Item | Confirmed information | Information still required |
|---|---|---|
| Machine | Reported as Daewoo ACE-V500s and ACE-500s | Exact nameplate model and machine year |
| Control | Fanuc 18i-MB | Machine-builder ladder and data-table documentation |
| Consumption | Approximately two tanks per day | Tank capacity, pump cycle frequency, and lubricant destination |
| Adjustment point | Not adjustable at the pump on this machine | Verified control timer or data-table location |
Locate the Machine-Builder Timer
The available evidence suggests that the lubrication interval may be stored as a timer in the control data tables. This remains a hypothesis, not a confirmed Fanuc parameter assignment. Do not substitute an undocumented Fanuc parameter or change an unidentified data-table value; the machine builder may implement lubrication timing in its ladder logic rather than as a standard control parameter.
- Record the exact machine model, serial identification, and displayed control designation.
- Observe and record when the pump starts, how long it runs, and where lubricant exits.
- Search the machine-builder documentation for lubrication timers and data-table assignments associated with the existing pump command.
- If the documentation does not identify the timer, request the model-specific setting from the machine distributor or DN Solutions service.
Verify the Correction
Before changing any value, save the original setting and confirm that the identified item actually controls the lubrication pump. After an authorized adjustment, observe multiple commanded cycles and verify that lubricant still reaches the intended lubrication points while discharge into the coolant tank or onto the floor decreases. Stop and restore the original value if lubrication delivery becomes uncertain.
Consumption should be compared over a consistent operating period. Because tank capacity, required cycle interval, and acceptable consumption are not provided, the evidence does not support a target timer value or a normal tanks-per-day figure.
FAQ
Which Fanuc 18i-MB parameter adjusts the ACE-V500s way-lube pump?
No verified parameter number is available in the evidence. The timing may be implemented in machine-builder data tables or ladder logic, so obtain the assignment for the exact machine model.
Can the way-lube timing be adjusted at the pump?
The reported pump cannot be adjusted at the pump itself. Investigate the control-side timer only after confirming its documented data-table or ladder assignment.
Does two tanks of way oil per day prove the timer is wrong?
No. Two tanks per day is the reported symptom, but lubricant entering the coolant tank or reaching the floor can also indicate a leaking, disconnected, or misdirected path; observe the system during a pump cycle before changing timing.
