5. Precautions for Use
5.5 Air Purge
The robot will conform to the IP65 dust-proof/splash-proof specification when the pressure specified below
is supplied from the air inlet provided on a side face of the base.
x The user must provide the air supply (pressure-reducing valve, etc.) and air tube (I6).
x The speed controller has already been adjusted to an appropriate flow rate corresponding to the
specified pressure. The needle need not be readjusted.
Supply pressure 0.2 to 0.3 (MPa)
Pipe size Outer diameter I6 x Inner diameter I4
Purge medium
Clean, dry air free from compressor oil, etc., corresponding to an air filtration
rating of 10
Pm or below. The dry air must have an atmospheric dew point of
–20 qC or below.
z Be sure to use clean, dry air with an atmospheric dew point of –20qC or below. If air is not fully dry,
bedewing will occur and water will collect inside the robot, resulting in current leaks or malfunction.
z Do not supply air compressed to pressures beyond the specified level of 0.3 MPa. The seal may be
damaged and the dust-proof/splash-proof function of the robot may be lost.
z The speed controller has already been adjusted, so do not adjust the needle again. Readjustment
of the needle may reduce the dust-proof/splash-proof function of the robot.
