SP2: Pressure Switch for Unclamp Detection
SP2: Pressure Switch for Unclamp Detection
The air purge is performed by air branched inside of NC table that uses air for clamp.
Be sure to use the clean air (passing through air filter, mist separator, regulator and drain
catcher) passing through the filter. If the air contains water content (moisture), oil content,
etc., it is entered in the motor cover, thus causing in equipment damage. The air inside of
motor case is exhausted from the air exhaust port.
In case that the portion of the air closed, motor case or motor etc. may be damaged so that
the dew cannot be exhausted and that air pressure is kept in the motor case. Therefore the
portion of exhaust should not be closed.
When exhausting, though exhaust sound occurs, there is no trouble.
7-4. Confirmation of Clamp and Unclamp
The unit is equipped with two built-in pressure switches for clamp/unclamp detection as
shown in Fig.1-1
～
1-5.
The set up pressure of each switch for pneumatic systems is as follows
：
Signal Clamp Signal (SP1) Unclamp Signal (SP2)
Pneumatic 0.25 MPa
PS1000-R06L-Q-X140
0.055 MPa
PS1100-R06L-Q-X141
The pressure switches SMC CORP made are used.
