Deadband
*If your application requires lower velocities or payloads, you may be able to reduce
the minimum recommended deadband setting, or if your deadband requirements can
accommodate a large range, you may be able to increase your payload higher than the
recommended values.
**Note: Use the Formulas in the Glossary to convert the Minimum Deadband shown
in the table to displacement.
Assumptions used for Sizing Values recommended above:
• Values shown above are with no overshoot. If overshoot is acceptable for your
application, the Deadband may possibly be less than specified above. However,
be sure your system cannot go unstable. Refer to Caution statement on page 20.
• PFC cylinder with Option L is used. (Option L has very low friction seals. The
standard PFC utilizes a rod wiper which increases friction significantly, which
will have adverse effects on positioning capabilities).
