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.
Bare actuators:
Units:
“Note: The knob on the end of the drive screw provides inertial mass required for operation. Removal of the knob will prevent the Picomotor from functioning properly and void the warranty.”
4-pin RJ-22:
Has note saying that the two GNDs are electrically connected.
There seem to be at least two different driver systems: “intelligent” / network system and stand alone drivers.
“The Picomotor drivers generate the 130-V pulses required to drive the piezo in the Picomotor.”
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.

Additionally:
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.
