 +One thing I wasn't expecting to be prepared for.  Piezos are used for loudspeakers...drive frequency is 2 kHz.  Get it?  Very loud and annoying :P  They do however work well.
 +
 +They are also reasonably low torque.  Will do some experiments to see how they drive some of my linear stages.

-Basically a controller receives input from either a joystick, pendant, ethernet, or RS-232 which then relays a signal to RS-485 daisy chained (Distributed Control Network (DCN)) open and/or closed loop drivers.  Free Windows DLL available (advertised in manual, haven't looked into it).  Runs off of 24VDC using standard Phoenix Contact Combicon compatible quick disconnects.  +Basically a controller receives input from either a joystick, pendant, ethernet, or RS-232 which then relays a signal to RS-485 daisy chained (Distributed Control Network (DCN)) open and/or closed loop drivers.  Free Windows DLL available (advertised in manual, haven't looked into it).  Runs off of 24VDC (min/max varies) using standard Phoenix Contact Combicon compatible quick disconnects.

 +====== Precision / repeatability ======
 +
 +According to manual, step size varies considerably.  Standard drivers < 30 nm, Tiny < 100 nm.  From standstill or changing direction will cause significant variance.  Other factors include direction, load, temperature, and wear.
