For multi-axis configurations special attention needs to be taken into account for the moving cables on 
the non-base axis.   

 

. 

Consider using the top axis for the highest frequency move in the application.  The top axis will have 
the least amount of weight to move and will reduce the cycles on the cables.

For ‘Z’-axis (vertical) applications, the use of the pneumatic counter balance and accessory kit is 
strongly recommended.  The pneumatic accessory kit includes a filter-regulator-precision regulator, 
fittings and 1/8” ID tubing.  The pressure in the pneumatic cylinder can be set to provide a balancing 
force to counter act the effect of gravity.  The counter balance force (F

C

) is a linear function of the 

pressure (P) and the cylinder piston area (A

C

); F

C

 = PxA

balance force.

The yaw force generated by the counter balance will add 0.2 arc-sec of yaw per psi of pressure.   
 
The Pressure regulation during motion is dependent on the speed and acceleration of the motion 
profile.  The following table shows the expected pressure fluctuation based on the move dynamics.

The vertical counter balance is compatible with clean rooms of class 250-500 for speeds below 500 
mm/sec or class 1000 for higher speeds due to the particle generation on the plunger.
