Npaq 6U high-power drive rack from Aerotech

Featuring high-performance, double-precision DSPs, the Npaq 6U performs both current loop and servo-loop closures digitally to ensure positioning accuracy and rate stability. It is this processing capability that allows the Npaq 6U to provide loop closure rates up to 20kHz and to handle both digital and analogue I/O processing, data collection, laser firing and encoder multiplication tasks in real time.

Standard options for the Npaq 6U include integrated encoder multiplication, per-axis brake control logic, I/O expansion and integrated emergency stop circuitry. The Npaq 6U contains two configurable power supply sections rated at 600W each to support a variety of motors with different operating voltages. When only one motor voltage is required, the power supply sections are joined together for even higher power capability.

The Npaq 6U has a dedicated Ethernet port to communicate with third-party I/O modules for increased I/O count applications. It supports up to three axes of Position Synchronized Output (PSO) for precise synchronising of external devices, over-voltage shunt controller and external fans for high-power operation.
