14 - 3 Air Pressure Adjustment
Regulate air pressure between 0.25 - 0.30MPa (speci¿ed air pressure).
Setting parameter (refer to P108 " 18 - 4 ⑨Selection of Air Input Monitoring Override " section), allows
the motor to run at 30,000min-1 (rpm) without motor cooling.
Running the motor 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
・If air pressure is too low, the motor will not operate.
If the supplied air pressure remains lower than the specified air pressure for 3 seconds or more while
the motor is rotating, the motor will stop automatically. If the supplied air pressure becomes lower
than the supplied air pressure while the motor is rotating, Warning code " A1 " will be displayed on
the Digital Speed Indicator ⑬and a warning signal (WARNING) will be output.
・The cooling air also provides air purge protection to the motor spindle. If the Main Power Switch ⑨is
turned OFF, the cooling air will continue to Àow.
・When using the CONTROLLER without supplying cooling air, change setting parameter " Setting
Air Input Monitoring Override " to . When using the motor without supplying coolant air, pay
attention to any temperature increases of the motor spindle.
・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 spindle.
・Never supply over regulated air pressure. There is a possibility to damage to the air detection sensor
inside the CONTROLLER. If excessive air pressure is supplied, Warning code " A5 " will be displayed
on the Digital Speed Indicator ⑬and a warning signal (WARNING) will be output.
・The air detect function within the CONTROLLER detects air input supply only. If any problem such
as damage to the air hose connected to the Air Output Joint ⑧occurs, the air pressure will not be
supplied to the motor and thus the air pressure will be undetectable.
