Clamp Close
Three separate clamp close profiles may be configured:
first close
second close
third close
You may select from these control modes:
velocity vs. position
pressure vs. position
Use Clamp Close to move the platen from the fully open position (L) to
some position X at a relatively high velocity or pressure. X is a position
relatively close to the stationary platen yet far enough away to allow
deceleration into Low Pressure Close. This prevents the platens from
coming together at a high velocity.
