Mori Seiki CNC Turning Center NL1500/500

Display the 'PERIODICAL INSPECTION 1' screen. If the cumulative time is close to inspection time, replace the NC memory back-up battery and SERVO absolute position sensing battery and reset the cumulative time.

1. Change the NC memory back-up battery and servo absolute position sensing battery with power supplied to the NC. If the batteries are changed with the NC power supply turned OFF, the data stored in the memory may be lost.

2. Before changing the batteries, save the memory data such as parameters and programs as backup in an external I/O device such as a memory card or USB memory. Mori Seiki is not liable for problems that result from destroyed programs or lost data that have not been backed up.

3. Always ensure that the polarity of the batteries is correct. If the polarity is reversed, the memory data may be lost when turning OFF the NC power.

CAUTION: If the oil level decreases rapidly, the pump unit or the machine may be malfunctioning. Contact the Mori Seiki Service Department for assistance.

CAUTION: Maintain oil at the correct level to prevent air being suctioned through the pump unit.

CAUTION: Keep oil free from contamination.

CAUTION: If foreign matter accumulates in the tank, oil cannot be kept free from contamination, causing pump damage.

CAUTION: Clogged radiator causes oil pressure to be raised.

CAUTION: Clogged suction strainer causes pumps and piping damage.

CAUTION: If the oil pressure setting is incorrect, hydraulic unit malfunction and damage may result.

For oil types, refer to “OILS” (page 59).
