Air Hose Connection - Nakanishi E3000 Operation Manual

14. AIR HOSE CONNECTION

CAUTION
When not using NAKANISHI Air Line Kit, make sure that the incoming air supply is dry, clean
and properly regulated.
( 1 ) Insert the provided
the front of the CONTROLLER.
( 2 ) Insert one end of the provided
( 3 ) Insert the other end of the
CONTROLLER using the provided Reducer ( 6 mm -
( 4 ) Regulate air pressure between 0 . 25 - 0 . 3 MPa ( 36 . 3 - 43 . 5 psi).
Setting parameter
" 18 - 4 ⑦
Selection of Air Input
Monitoring Override" section), allows
the motor to run at 30 , 000 min
without motor cooling.
Running the motor and spindle
without cooling can cause premature
failure due to high temperatures.
Limit the usage of parameter to
" Selection of Air Input Monitoring
Override " (startup motor without
supplying cooling air) to only when
supply cooling air is not suitable or
available.
CAUTION
・ The Air input joint ⑦ , is designed to accept cooling air between 0.25 - 0.3MPa (36.3 - 43.5psi).
If the air pressure is too low, the CONTROLLER will not operate and an Error code will be
generated.
・ The cooling air also provides air purge protection to the motor spindle. If the Main Power
Switch ⑨ is turned OFF, the cooling air will continue to ow. When using the CONTROLLER
and SELECTOR without supplying cooling air, change setting parameter "
Input Monitoring Override " to ON. Never spray coolant directly on the spindle body without an
air purge.
・ When using the SELECTOR, do not use Air input Joint ⑦ nor Air Output Joint ⑧ of the
CONTROLLER. Install the provided Air Plug ((
Input Joint ⑦ and Air Output Joint ⑧ . The Air Input can be directly connected to the SELECTOR.
・ Do not make any sharp bends in the air hose, or pull on the hose as this can cause the hose to
break, cut off the air supply or weaken the hose over time resulting in deterioration of the motor
and spindle.
・ Attach the provided Connector Cover for safety and dust proo ng when not using the External
Input / Output Connector A ③ , B ④ , or Serial I / F Connector ⑤ of the CONTROLLER.
・ Never supply over regulated air pressure. There is a possibility to damage to the air detection
sensor inside the CONTROLLER.
・ The air detect function within the CONTROLLER detects air input supply only. If the Air Out hose
is damaged from the CONTROLLER, it will not be able to detect the lack of cooling and purging
air to the motor spindle.
