  • Page 6: Introduction

    Charge is transferred to the piezo actuator using low-loss PWM techniques. When the actuator is discharged, the energy not consumed is fed through the energy recovery circuitry for reuse in the next charging cycle. The working principle of the E-617 www.pi.ws E-617 PZ201E Release 1.1.1...
  • Page 7: Prescribed Use

    Prescribed Use Based on their design and realization, the E-617 High-Power Piezo Amplifiers are intended to drive capacitive loads, in the present case, piezoceramic actuators. The E-617 must not be used for applications other than stated in this manual, especially not for driving ohmic (resistive) or inductive loads.
  • Page 8: Safety Precautions

    When working with these devices or using PZT products from other manufacturers we strongly advise you to follow general accident prevention regulations. Allow operation of the E-617.00F module only after it has been installed in a proper housing which provides protection against the exposed conductors with high voltages.

    (Driver set can also be downloaded from www.pi.ws: see included technical note E500T0011 for instructions). The E-617 can be controlled via a signal connected to its analog input line (see "Using the Analog Input" for more information). This signal can, for example, be generated using a D/A board in a PC.

  • Page 13: Start-Up

    Operation 2.1.3 Start-Up On the main board of the E-617 modules a DC-DC converter is installed with a 23 to 26 VDC input voltage range. The converter generates -30 and +130 V for the power amplifier. Optionally, connect an external 10 k-ohm potentiometer to the control input sockets using the included 6-pin connector.

    DC signal in the range of -2 to +12 V (-3 to +13 V are possible but working with increased output voltage will decrease actuator lifetime, see p. 19 for details). See section 2.3.4, p.14, for information on PI support of external operation with a DAC card in a PC. 2.3.2...

    Computer Control & Hyperbit Computer control of an E-617 can be realized using a DAC- board in a PC to generate the analog input signal. PI offers a LabVIEW driver set which can be used with certain D/A boards. This driver set is compatible with the PI General Command Set (GCS) LabVIEW driver set available for all newer controllers from PI.

    This must always be taken into consideration in an application. The recommended maximum range of the control input voltage for E-617 therefore is -2 to 12 V, resulting in a piezo voltage range of -20 to 120 V. A control input range of -3 to 13 V is possible (results in -30 to 130 V piezo voltage), but will reduce the actuator lifetime accordingly.

    With the E-617 amplifier output, this means that a low- frequency signal seems to be measured which is not present at all.
