7.4.2 connecting piezo actuator
Piezo electrical actuators are connected to the amplifier unit by using the D-SUB connector
on the back panel. Please make sure that the amplifier is switched off when connecting /
disconnecting the PZT to the amplifier. Please fasten the screws of the D-SUB connector
and guarantee a firm connection. After switching on the initialization procedure follows.
(please see chapter 7.1) Then the display shows the details of the used PZT.
If the display shows the information “NOT CONNECTED” please check the connection
between PZT connector and amplifier again. Please note: during initialization procedure the
operation of the unit is disabled.
