6 Starting and Operating
P-2x5 Piezo Actuator
PZ245E
Version: 1.1.1
33
Variable
Description
Notes
I
a
Required average current of the
amplifier (source / sink) [A]
It is essential that the power supply can
supply enough current.
I
max
Required peak current of the amplifier
(source / sink) [A]
The provided peak current depends on
the internal storage capacity of the
amplifier.
f
Operating frequency [Hz]
Details on the operating frequency see
"Overview of Limiting Factors" (p. 30).
C
Capacitance of the piezo actuator
[F (= As/V)]
See "Data Table" (p. 41) for the small-
signal capacitance of the piezo actuator.
For large-signal conditions, a safety
factor of 70 % should be added to the
small-signal capacitance.
U
p-p
Operating voltage (peak-to-peak) [V]
Voltage difference between positive and
negative peak voltage
