Minimum Frequency can be set to an integer value between 1 kHz and the Maximum Frequency. If this value is adjusted above the Current Frequency, the Current Frequency is adjusted to comply with the Minimum Frequency. Power. If the power dissipated in the actuator is greater than this value, the actuator power reading in the status panel changes to bold red text to alert the user. -

Target Phase of the current relative to the drive voltage. This is equivalent to the phase of the admittance, which is the inverse of impedance. Negative values indicate a current lag (inductive), and positive values indicate a current lead (capacitive) ... -
Page 10: Frequency Sweep Mode
Figure 5. Resonance control with power tracking 3.6 Frequency Sweep Mode In the frequency sweep mode, the impedance of the transducer is measured from the set Minimum to Maximum frequency. Since many ultrasonic actuators exhibit a non-linear resonance at high-power, the frequency is swept in both directions. -
Page 11: Dynamic Range
In the Frequency Sweep mode, the available controls are: Driving Amplitude Peak to Peak Maximum Frequency Minimum Frequency Start/Stop button. In addition to the impedance measurement, the transfer function between the voltage and an auxiliary signal can also be measured simultaneously by applying an auxiliary signal to the front panel. Typical signals include the acceleration, velocity, or displacement. -

The actuator can be connected to the amplifier by either two 4mm banana plugs or a 2-way LEMO 0B socket (LEMO EGG.0B.302.CLL). Preassembled LEMO cable assemblies are available from www.PiezoDrive.com The mating plug is a LEMO 0B 2-Way Straight Cable Plug. Ordering details and specifications are listed below. -

Page 14: Overload Protection
Overload Protection 4.2.1 Shutdown Indicator The Shutdown indicator will illuminate during a shutdown caused by a current overload or if the amplifier overheats as a result of excessive ambient temperature, poor air-flow, or fan failure. During shutdown, the amplifier output current is limited to a few mA and may float to the high or low voltage rail if the load impedance is high. -
Page 15: Installation
The documentation and program files for the API can be obtained by contacting info@piezodrive.com The desktop software for the PDUS200 uses the API so the source code is a useful programming example. This is included in the API package.
