The PDU-S1 is a medium power, brushed PWM servo amplifier in a 3U Eurocard form factor. Control can come from an analog (±10V) command, or digital Magnitude and Direction signals. This multi-purpose amplifier contains both Velocity and Torque feedback loops. Inputs are provided to allow tachometer feedback in the Velocity Mode. The Torque Mode can be used for torque control applications, or in conjunction with a digital servo controller capable of computing Position and Velocity loop values. The high switching frequency of the PAU-S1 allows the amplifier to drive very low inductance loads.
The PDU-S1 has Under Bias Voltage shutdown as well as Over Current and Over Voltage protection. Fault conditions are reported digitally to the controller connections, and indicated visually by front panel LEDs.
An optional backplane is available to allow quick and easy access to motor, power, control and other I/O signals. This greatly simplifies implementing the PDU-S1 in a motion control system.
