Span Your Valves
This chapter describes how to span your valves using direct-output
operation, and verify by running simple open-loop profiles.
ATTENTION: Before proceeding, be sure you completed all
previous chapters. Failure to do so could result in unpredictable
machine motion, with possible equipment damage and/or injury.
We show you how to span these valves:
injection pressure valve
injection velocity valve
pack/hold pressure valve
plastication pressure valve
plastication screw RPM valve
We also describe how to:
test valve linearity
set profile pressure alarms
