Product Description:
The PRD-0051AMPE-X0 belongs to the VRDM Servo Amplifiers series manufactured by Kollmorgen. It functions as a servo amplifier, converting power from a fixed DC bus into controlled three-phase AC for regulating motor speed and torque in automated material-handling lines, pick-and-place cells, and packaging stations. By closing the electrical loop between motion controllers and servomotors, it supplies precise current waveforms for rapid indexing and accurate position holding. This conversion allows the connected motor to respond to changing motion commands while maintaining stable operation under varying loads.
The power stage accepts a bus voltage of 350 VDC, and its input circuitry draws up to 9 A while charging internal capacitors and supplying the gate drivers. On the output side, insulated-gate devices produce up to 230 VAC line-to-line for the motor terminals. The amplifier supports a continuous phase current of 15 A, allowing it to supply sustained motor loads without exceeding its continuous current rating. Carrier and fundamental switching logic provide a programmable output frequency range of 0–400 Hz, supporting low-speed holding torque and high-speed movement from the same motor. These electrical limits must be considered when matching the amplifier to the motor’s back electromotive force, winding resistance, current demand, and thermal capacity.
Control and communication signals are routed through a female DB25 AMP-Control connector, which carries analog references, enable signals, and fault outputs between the amplifier and the supervisory PLC. The unit also has two IEEE 1394 FireWire ports for deterministic network communication, allowing it to occupy an intermediate position in a multi-axis chain without additional hubs. Internally generated phase sequences leave the amplifier as a balanced three-phase waveform compatible with standard brushless motor configurations. The communication ports also support diagnostics and parameter transfers across coordinated motion systems. This arrangement reduces the number of separate network connections required when several amplifiers operate together in distributed automation equipment.
