Floating Load Configuration; Input Connection Diagram - PiezoDrive PD32 Manual

4.2 Floating load configuration
The floating load configuration is useful for achieving higher peak‐to‐peak voltage swings. The connection
diagram is illustrated below. Do not connect either of these signals to ground, for example, an oscilloscope
probe.
The desired output voltage range can be selected from the following table.
5 Input Connection Diagram
The front panel input connector is an industry standard DB37 Female Connector (TE 1658612‐1). Any Male
DB37 cable plug is compatible. The connection diagram is illustrated below.
