Operation Procedures - Nakanishi E3200 Series Operation Manual

9-4 Air Hose Connection
( 1 ) Connection of Air Input Joint
Insert the provided ø6mm filtered air hose from the AL-0201 air line kit into the Air Input
Joint [ 12 ] on the front of the selector unit. ( If you are not using the AL-0201 air line kit make
sure that the incoming air supply is dry, clean air. )
( 2 ) Connection of Air Output Joint
Insert one end of the provided ø4 mm cooling air hose into the Air Output Joint [ 4 ] [ 6 ] [ 8 ]
[ 10 ] on the front of NE261. Attach the Plugs to unused Air Output Joints. Insert another
end of air hose to air joint at the rear of the motor spindle.
( 3 ) Regulate air pressure 0.35MPa.
The system can be set to operate without cooling air. Please see parameter setting
(NE260) to set this option. Maximum speed is 30,000min
Note : It is not recommended to use the system in this manner for general machining.
This setting is only for light cutting and not for use with coolants.

CAUTION
1. Regulate the air supply 0.35MPa. If the air pressure is too low the control unit will
not operate.
2. When you don't use a motor connection, insert Plug to unused Air Output Joints
[ 4 ] [ 6 ] [ 8 ] [ 10 ] to avoid Air Flow. Attach the provided connector cap to unused
Motor Output Connectors [ 3 ] [ 5 ] [ 7 ] [ 9 ] .
3. When using Selector Unit NE261, don't need to supply the cooling air to Control
Unit NE260. Insert the provided Plug into (ø 6 ) Air Input Joint and Air Output Joint.
4. The cooling air also provides air purge protection to the spindle. If the Power
Switch [ 14 ] is turned off, the cooling air will continue to flow. When using the
E3200 without supplying cooling air, do not spray coolant directly on the spindle
body.
5. Check that cooling air is being supplied to the motor/spindle and ensure that the
cooling hose is properly connected to the motor and the NE261. Failure to
connect the hose properly or supply the proper amount of cooling air to the
motor will cause damage to the motor and spindle.
6. When you are plumbing the hose, take care not to apply excessive force to the
hose, it can easily become bent or broken. Failure to supply proper air may cause
damage to the motor spindle.
7. Never supply over the regulated air pressure. There is a threat to damage to the
air detect sensor inside the control unit.
8. The air detect function with the control unit is the detector of the input only.
When damaging to the air hose of the output of the control unit, can't be able to
detect no air supply to the motor spindle.

OPERATION PROCEDURES

1. Select Control Mode ( MANUAL /AUTO )
•Using the control switch on the NE260 you can
select between Manual ( Front Panel Control ) or
Auto ( External Signal Source ) modes. External
Signal Source can be used to control Motor
Start/Stop, Rotational Direction, and Motor Speed.
•Manual Mode-Front Panel Operation.
•Auto Mode-Control by External Signal Source.
2. Setting motor rotating direction, gear ratio ( GEAR ) , Motor Start/Stop, Motor Speed
2-1 Manual Mode Operation
When using Manual Mode with the NE260 and NE261 combination the following functions
will be controlled from the front panel of the respective units.
