Position Servo Control
For Strain Gages & LVDT Sensors
RS-232 Computer Interface with 12 bit D/A Converter

E-662 is a bench-top, amplifier/position servo controller with integrated RS-232 computer interface and 12 bit D/A converter for Low Voltage PZTs. The amplifier can output and sink a peak current of 360 mA and an average current of 120 mA. The position servo controller works with either strain gage sensors (E-662.SR) or LVDT sensors (E-662.LR). E-662 can be operated in 6 ways:

I. Open loop (amplifier mode)

Manual operation

Output voltage can be set by a 10-turn, DC offset potentiometer in the range of 0 to 100 V.

External operation

Output voltage is controlled by an analog signal applied to the BNC input ranging from -2 to +12 V. Multiplying by the gain factor of 10, an output voltage range of -20 to +120 V results. The DC offset potentiometer allows for a continuous variation of the input voltage range between -2 V to +12 V and -12 V to +2 V (click here).

Computer Control (toggle switch selected)

Output voltage is controlled via the RS-232 computer interface in the range of 0 to 100 V with a resolution of 12 bits. The DC offset potentiometer and BNC analog input are inactive when in computer control mode.

II. Closed loop (position control mode)

Manual operation

Displacement of the PZTs can be set by a 10-turn, DC offset potentiometer in the range of zero to nominal displacement.

External operation

Displacement of the Piezo 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 with maximum nominal displacement and 0 V corresponds with 0 displacement. The DC offset potentiometer can be used to add an offset voltage of 0 to 10 V to the input signal.

Computer Control (toggle switch selected)

Displacement of the Piezo is controlled via the RS-232 computer interface in the range of 0 to maximum nominal displacement, with a resolution of 12 bits. The DC offset potentiometer and BNC analog input are inactive when in computer control mode.

More than 40 SCPI (Standard Commands for Programmable Instruments) ASCII commands are available to program the E-662. An internal function generator provides sine, square, ramp and triangular functions up to 150 Hz. User defined functions can be stored in a table with up to 200 entries. Minimum time between two samples is 1 msec.
