The Series 2000 passive devices are a low cost solution for less demanding force control applications.  The Series 2000 is a low cost solution to your compliant tooling needs.

 

Lacking the Series 1000's sensors and electronics, the Series 2000 provides adequate performance for many rough grind and buffing processes which can tolerate greater force variation.

 

The Series 2000 comes in three configurations:  AFD2000-1 Vertical, AFD2000-2 Horizonta and AFD2000-3 Table Top.  The units are functionally identical, but differ in their mounting orientation.  This allows you to optimize robot reach and dexterity for your particular application.

 

Here are just a few of the many operations the Series 2000 can do for you faster, more reliably than ever before:

The Series 2000 passive force control tools provide a low-cost solution to operations requiring less precise force control.  Passive force control tools are less expensive than active tools because they use a simple, open-loop force control scheme.  Open-loop control schemes do not monitor forces being applied to a surface, thereby limiting their accuracy as compared to active force control tools.  This relegates passive force control devices to performing low speed operations on relatively flat parts with loose process requirements.

 

Implementing passive tools requires more time and integration skills than their active tool counterparts.  Since passive tools do not have a dedicated controller, more user supplied hardware and software support are required to operate the tools.

 

The Series 2000 passive tool has two analog voltage inputs which control pressures on each side of a pneumatic actuator.  The force applied by the tool is proportional to the difference of these two pressures.  Therefore digital to analog converters must be supplied by the user if automated control of the passive tool is desired.

 

Further complicating passive tool implementation is, that to achieve a desired force, the tool's orientation and motor weight must be known to calculate the appropriate pressure signals.  The calculations are relatively simple and the equations are provided, but if they are omitted, the only other means of achieving a desired force is through trail and error.

 

As you can see, using a passive tool to duplicate the features of an active tool requires considerable time and expense.  If advanced features and high performance are required, almost without exception, the overall cost of using an active device is less than using a passive device.  If however, your process is relatively simple and process tolerances are not critical, the Series 2000 passive tool will provide a rugged, low cost solution.
