Product Description:

Kollmorgen produces the PDD0410165 as part of its PD Servostar Servo Drives series. The unit is a panel-mounted servo amplifier that controls two brushless axes, converting low-voltage DC power into synchronized phase currents for industrial actuation tasks such as pick-and-place gantries or small autonomous vehicles. It accepts command signals from a motion controller and returns position feedback, so it acts as the drive stage between the controller and the motors. Its compact format simplifies integration into distributed control cabinets found on packaging lines.

It runs on a bus voltage of 48 V DC, distributing power to both motors and limiting the continuous load to 10 Arms per axis. Both axes share the same thermal channel, but the drive allows 10 Arms surges lasting 500 ms to accommodate rapid acceleration. The control board provides differential command terminals that tolerate ±12.5 V, and the internal converter digitizes the input with 12-bit resolution for each channel. High-speed capture inputs accept pulse-train references up to 2.5 MHz, while separate quadrature counters track encoder streams up to 3 MHz and sine encoder signals up to 265 kHz. An auxiliary 5 V DC rail powers the feedback transducers, removing the need for external sensor supplies. The two embedded axis cards support control of two tightly coupled motors while reducing the amount of required wiring.

Switching devices modulate phase energy at 16 kHz, and the resulting current ripple has a frequency of 32 kHz, so the motor windings receive a nearly sinusoidal waveform. The duty cycle is capped at 92.5% to maintain voltage margin when the DC link drops. Control electronics and I/O are energized from a 24 V DC service line, and each isolated transistor output can source 24 V DC at 60 mA to actuate relays or optical indicators. Thermal monitoring disables drive power when the heat sink reaches 80 °C, protecting the semiconductors during stalled conditions.
