5.4. E-504 High-Power Piezo Amplifier, Energy Recovery
DANGER
High Voltage!
The E-504 amplifier can output up to 130 V. Touching this High Voltage can result in serious
or even lethal injury due to electric shock.
 Only authorized and qualified personnel must install, operate, maintain and clean the E-
504 amplifier.
 Operate the piezo actuator on the “PZT” socket only when it is connected to a protective
earth conductor.

Adds 0 to 10 V to the “CONTROL INPUT” signal (only relevant
in analog operation, see p. 17 for details)
E-504.00F only:
CONTROL INPUT
-2 to +12 V
SMB
In analog operation, this control input voltage gives the target
(either as voltage or position, depending on the servo mode).
The input signal should always be in the range of 0 to 10 V
(excursions to -2 or +12 V may cause overflow, especially with
servo on, and reduce actuator lifetime).
The control input range can be shifted using the “DC-
OFFSET”
potentiometer.
The control input voltage can also be a computer-generated
analog signal (e.g. from a DAQ board). You can use a PI
LabVIEW Analog Driver set to generate that analog signal.
See “
Analog Operation” on p. 17 for details.
