2.1 TORqUe ACTUATOR
Select the type of actuator the RSD200 will control
“pneumatic brake/clutch” or “drive or magnetic particle.”
2.2 UNWIND OR WIND
Select whether the RSD200 will control a wind or
unwind dancer arm.
The MINIMUM and MAXIMUM OUTPUT settings
override all other settings and allow the RSD200
OUTPUT to be limited. Generally the MINIMUM and
MAXIMUM will be set at 1 and 100% respectively.
These values may need adjustment for some applications.
example One: Air supply pressure exceeds the
maximum air pressure rating of a brake or clutch. For
instance, an I/P transducer can supply 125 psi to a brake
rated for 80 psi. The MAXIMUM OUTPUT % should be
set as follows:
MAXIMUM OUTPUT % = (maximum brake pressure /
supply air pressure) * 100 = (80 / 125)*100 = 64%
example Two: A pneumatic brake or clutch that is spring
disengaged; In this case the MINIMUM OUTPUT %
would be set high enough to overcome the spring and
allow the friction facing to lightly contact the rotor.
The STOPPED OUTPUT setting is used to limit how high
the output can go while the RSD200 is in STOPPED
mode. This value supersedes the MAXIMUM OUTPUT
value during stopped conditions. It is used in applications
when the machine is stopped and a small amount of
drag tension is desired on the web. If the STOPPED
OUTPUT function is not needed then make it equal to the
MAXIMUM OUTPUT value.
