Closed-Loop (Servo On) Mode - PI E-664 User Manual

E-664 LVPZT Position Servo Controller
3.2.

Closed-Loop (Servo ON) Mode

3.2.1. Manual Operation
Displacement of the PZTs can be set by a 10-turn DC-Offset potentiometer in the
range of zero to nominal displacement. For manual operation CONTROL IN should
clamped at 0 V.
3.2.2. External Operation
Displacement of the PZT is controlled by an analog signal in the range of 0 to +10
V, applied to the CONTROL IN BNC input. The controller is calibrated so that 10 V
corresponds to the maximum nominal displacement and 0 V corresponds to zero
displacement. The DC-offset potentiometer can be used to add an offset voltage of
0 to 10 V to the signal input, effectively shifting its range between -2 to +12 V and -
12 V to +2 V.
