5.5 Operation with Other Members of the K-Cube Family

5.5.1 Introduction
The operation of the KPZ101 piezo controller can be extended when the unit is used
in conjunction with other members of the K-Cube family. Specifically, 2 other
controllers have been designed to work closely with the KPZ101 piezo unit; the
KSG101 strain gauge reader and the TNA001 NanoTrak autoalignment controller.
When the KPZ101 piezo controller is used with a KSG101 strain gauge reader, closed
loop operation is possible, which allows more stable and precise position control than
open loop - see Section 5.6.
When used with the TNA001 NanoTrak controller and a laser light source such as the
TLS001 laser source cube, automatic fiber alignment systems can be built - see the
handbook supplied with the NanoTrak unit for more information.
With both the KSG101 and the TNA001 it is possible to build a system without the
TCH002 USB controller hub, however, in this case individual power supply and USB
connections are required for each controller in addition to the external signal cables
between the controllers. Using the TCH002 hub greatly simplifies the system because
the hub provides all the necessary power, signal and USB connections to all the
controller cubes.

5.6 Closed Loop Operation

The following procedures explain the basic operation of the Piezo Driver K-Cube
when used in conjunction with a Strain Gauge Reader K-Cube. Section 5.6.1.
explains operation on the TCH002 USB Controller hub, while Section 5.6.2. explains
the various bay mounting options and the associated software settings.
Section 5.6.3. explains use off the hub, with external wiring via the rear panel
connections.
When the KPZ101 is used in closed loop mode with the KSG101 Strain Gauge
5.6.1 Electrical Connections and Software Settings - Hub Operation
The following procedure describes a typical set up, when a KPZ101 piezo driver cube
and a KSG101 Strain Gauge Reader are used on the TCH002 controller hub to drive
a piezo actuated stage - see Fig. 5.7 for a general system schematic diagram.
Reader, it is not possible to modulate the KPZ101.
