Upgrades The E-471.00 version allows installation several upgrade options for enhanced versatility (see Ordering Information). Two additional modes are possible with versions having the E-509 Sensor & Servo-Controller Module upgrade: I. Manual Closed-Loop Operation Displacement of the PZTs can be set by a 10-turn DC-offset potentiometer in the range of zero to nominal displacement. II. External Closed-Loop Operation Displacement of the PZT is controlled by an analog signal in the range of 0 to +10 V, applied to the BNC input. The controller is calibrated in such a way that 10 V corresponds to maximum nominal displacement and 0 V corresponds to 0 displacement. The DC-offset potentiometer can be used to add an offset voltage of 0 to 10 V to the input signal. Notes Important Calibration Information: Please read details see PI main catalog page 6-53. | | |

| | | The E-470 series high-industrial power amplifier/controllers are specifically designed to drive high-capacitance PZT actuators. They are based on the E-420 4-quadrant amplifier module, which can output and sink a peak current of 500 mA and an average current of 100 mA in a voltage range of -3 to -1100 V (positive or bipolar range, jumper selectable). OEM, 19" rackmount, bench-top, and two-channel versions are available, some with servo-control module and display (see Ordering Information for standard combinations). | | Standard versions can be operated in two ways: I. Manual Control: The output voltage can be set by a 10-turn, DC-offset potentiometer in the range of -3 to -1000 Volts II. External Control: Output voltage is controlled by an analog signal applied to the BNC input, ranging from 0 to 11 Volts. Multiplying by the gain factor of -100, an output voltage range of -3 to -1100 Volts results. The DC-offset potentiometer adds a DC bias to the | | |
