possible to adjust the DC level on the output whilst adding an AC signal to this DC
level via the external SMA terminal.
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 othe r members of t he K-Cube family. Speci fically, 2 othe r
controllers have been designed to work cl osely with the KPZ 101 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
KCHx01 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 KCHx01 hub greatly simplifies the system because
the hub provides all the necessary po wer, signal and USB conn ections 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 Strai n Gauge Reader K-Cube. Section 5.6.1.
explains operation on the KCHx01 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 exte rnal wiring via the rear panel
connections.
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 KCHx01 controller hub to drive
a piezo actuated stage - see Fig. 5.8 for a general system schematic diagram.
Note
When the KPZ101 is used in closed loop mode with the KSG101 Strain Gauge
Reader, it is not possible to modulate the KPZ101.
