Product Description
3.1
Control of Bending Actuators
The E-651 / E-614 is designed and intended for driving of
PICMA
®
multilayer bending actuators such as the PL-112 to
PL-140, and P-871 from PI.
The PICMA
®
bending actuators require full differential-voltage
control with constant voltages of 0 V and +60 V and a variable
voltage from 0 V to +60 V (see
Fig. 1). Note that a control input
voltage of 5 V corresponds to a PZT variable output of about
+30 V, which puts the actuator in the middle position (i.e.
deflection
≈
0
μm).
