Problems with your Mantis piezo driver?


Introduction

The Mantis piezo driver was designed to operate with piezoceramic tubes similar to the ones produced and distributed by Boston Piezo Optics (open product page). These piezo tubes are made of 4 quadrants opposing each others in pairs. Each pair produces a displacement in one axis. Each pair is connected to one BNC output of the Mantis piezo driver.  


Hardware

Input side of the driver

The Mantis piezo driver takes 5V DC in (up to 1.5A).

The power supply works correctly if the orange LED is ON.

The two BNC connectors are DC control inputs from a DAQ (data acquisition card) or from a signal generator. The input range is 3.8V (min = 0.7V and max = 4.5V). They each control one axis of the piezoceramic tube actuator.

Power supply requirements:

5V DC, positive center, up to 1.5A.

Output side of the driver

The output side of the box, with the ON/OFF button.

When the driver is powered ON the LED in the middle turns green. If not, see if the orange LED on the input side is let. If not, check the power supply.

The output female (left) connector receives its male counterpart below.  

Male output connector. Brings high voltage to the piezoceramic tube actuator.

The output connector is plugged simply by pushing it in. The orientation is fixed, there is only one way to push it in.

To disconnect simply pull it out.

WARNING!  Isolate not connected wires ends.

Wire connections to the piezoceramic tube actuator.

  • Brown and White are ground.
  • Pink and Blue for Channel B+ and B-, respectively.
  • Yellow and Grey for Channel A+ and A-, respectively.

WARNING!  Always turn off the power before working on the given circuit to avoid electrical shock.

Connections to the data acquisition (DAQ) card

The Mantis piezo driver takes in DC voltage on a ~3.8V range, min = 0.7 and max = 4.5. A DAQ (data acquisition card) or a signal generator is needed to drive it.

In order to drive 2 axis one needs 2 analog outputs. Simply connect each analog out to the BNC input connectors of the piezo driver.

The center wire of the BNC is connected to an analog out of the DAQ card. The analog out ground pin of the DAQ card is connected to the casing.  

Examples of DAC cards and connections

The pictures below show two examples of low cost DAQ cards that can be used with the Mantis piezo driver. The red wire goes to the middle of the BNC cable and the black one goes to ground.

SENSORICA’s open DAQ, see webpage.

We also strongly recommend RedPitaya, which also has an FPGA that allows real time control.


Software

Some of our customers and collaborators use IAC’s LabView platform for controlling the Mantis piezo driver and for integration with other equipment.
