14 - 2 Two Motor Spindles are connected
to the CONTROLLER (Fig. 18)
(1) Insert the provided
from the Air Line Kit AL-C1204 into the Air Input
Joint ⑦ on the front of the CONTROLLER.
(2) Insert the Air Branching Joint (standard
accessories) to the Air Output Joint ⑧ .
(3) Insert one end of the
(motor cord's standard accessories) into the Air
Input Joint on back of the motor spindle.
(4) Insert the other end of the
Hoses into the Air Branching Joint (standard
accessories).
14 - 3 Air Pressure Adjustment
Regulate air pressure between 0.25 - 0.30MPa (speci ed air pressure).
Setting parameter
the motor to run at 30,000min
Running the motor spindle without cooling can cause premature failure due to high temperatures.
Limit the usage of parameter to "
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 ⑬ and a warning signal (WARNING) will be output.
・ 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 without supplying cooling air, change setting parameter "
Air Input Monitoring Override " to
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 ⑬ and 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 ⑧ occurs, the air pressure will not be
supplied to the motor and thus the air pressure will be undetectable.
