commons are connected together on the user end to avoid D.C. offset errors.
6.0 Achieving Desired Force
6.0.1 Table Top
The
AFD92
is a passive force device that requires the user to provide pressure to the
pneumatic actuators. Pressure in the actuators results in an output force at the
Carriage. If the AFD is a table top unit, and/or always in the horizontal position or does
not change orientation achieving the desired output force is easy. The passive force
device requires the user to provide regulated air pressure to achieve a desired force
output. Use the following equations for a table top unit to determine the pressure
required to achieve the desired output force:
