You control clamp operation with these phases:
clamp close
low pressure close
clamp open
open slow

Clamp Close
You may configure three separate clamp close profiles:
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 (Figure 1.10).
