Was diese Zeichnung zeigt
Die dahinterstehenden Entscheidungen verstehen.
01Cycle start
A pushbutton begins the clamp command.
02Position feedback
A limit switch signals that the clamp has reached its position.
03Release output
A second relay and solenoid command the release valve.
Use as a starting control sequence for a fixture or press clamp, then add timing, guarding, and safety logic for the machine.
FAQ
Häufige Fragen
What is a clamp limit switch for?
It provides position feedback when the clamp reaches a defined point in its travel.
Why use a separate release solenoid?
It commands the directional valve to move fluid in the direction that opens the clamp.
Is this sufficient safety control for a press?
No. Press and clamping safety requires a machine-specific risk assessment and appropriate guarded safety controls.
