E-664 LVPZT Position Servo Controller

Quick Start

The E-664 PZT Controller was calibrated with the PZT translators before shipment.
During the calibration process, the expansion of the PZT is compared with an
external standard scale. Individual characteristics of the amplifier and servo-
controller are compensated.

Starting Operation

1. Being sure not to exceed allowable force limits (see p. 19 for details), mount
the NanoCube mechanics carefully.
2. With the controller powered down, connect the NanoCube to the STAGE
socket.
3. Set the servo switch to OFF and the DC-OFFSET potentiometer counter-
clockwise (CCW) to the hard stop. Switch the display to VOLT.
4. Make sure the power supply is set to allow operation at the proper voltage
range. Two ranges are available: from 100 to120 V and from 220 to240 VAC.
The line fuses need to be replaced when the supply voltage range setting is
changed (see p. 17 for details).
5. Connect the line cord and switch the power on.
6. First watch the VOLT display while turning the potentiometers clockwise. It
should be possible to reach 100 V. Turn the pots back full CCW.
7. Switch display to MICRONS (µm). The values should be close to zero (±20
µm).
8. Switch SERVO to ON. Every channel should now have 0.0, the OTG (on
target) LED should be on, the OFL (overflow) LED off.
9. Turn potentiometers again to maximum. It should be possible to reach 100.0
µm on every channel.
10. If any channel does not operate correctly, switch it to VOLT and see how
much piezo voltage is needed. Typically for 0 to 100 µm, the piezo voltage
should be
range with the associated ZERO-potentiometer (see
Calibration
possible that ZERO needs to be corrected.
The above procedure assures that the system is working correctly in manual
mode.
