Air Hose Connection And Air Pressure Settings - Nakanishi iSpeed3 Operation Manual

15 . AIR HOSE CONNECTION AND AIR PRESSURE SETTINGS

15 - 1 Air Hose Connection
CAUTION
Regulate the air pressure between 0 . 2 - 0 . 5 MPa. If inlet air pressure is too low the control unit
1.
will not operate and an error E 7 occur.
The cooling air provides two functions, to cool the electric motor and to protect the spindle
2.
from contaminants by providing a positive airflow.
3. Do not make any sharp bends in the air hose. Do not pull sharply on the air hose, as this can
cause the air hose to break , cutting off the air supply or weaken the air hose over time.
This will result in the deterioration of the motor and spindle.
Never supply over recommended regulated air pressure. There is a possibility of damage to the air
4.
detection function within the control unit. This detector recognizes air input only, not air output.
5. If there is damage to the Air Out hose, the control unit is not able to detect that there is no air
being supplied to the motor spindle. This will cause premature motor spindle failure.
Insert the provided
of the control unit. (If you are not using the AL-0201 Air Line Kit make sure that the inlet air supply is dry, clean,
regulated air.)
Insert the provided
Insert the other side of the φ 4mm air hose into the Air Output Joint on the rear of the control unit. When
connecting two motor spindles to the control unit, use the Air Branching Joint that has been provided.
This Air Branching Joint is to be used with only 2-Meter, 3-Meter and 5-Meter Motor cord/Air Lines.
Motor Spindles cannot be connected to the control unit when using a 7 -Meter Motor Cord/Air Line.
Set the air supply pressure according to Section 15-2 "Setting The Air Supply Pressure" table 2.
15 - 2 Setting The Air Supply Pressure
The air pressure requirement varies with the number of the motor connections and the length of the air hose (Quick Disconnect
Cord and Motor Cord). Verify the number of spindles and motor cord length before setting the pressure according to Table 2
