Aerotech Ndrive series digital servo drives

Series Overview

The Ndrive series digital servo drive is a high-performance discrete drive option for the Automation 3200 motion system, featuring the following features:

Driving capability: It can drive brushless motors, brushed DC motors, and stepper motors, execute current loop and servo loop closure, and ensure high-level positioning performance and speed stability.

Processing capability: Equipped with a high-performance digital signal processor (DSP), it can perform complex calculations in real-time. The sampling rate of the digital current loop and servo loop can reach 20kHz, and it can also handle digital and analog I/O, laser triggering, and encoder multiplication.

Network and Expansion: Some models (such as HP and HL) have optional dedicated Ethernet ports that can communicate with I/O modules from third-party vendors; Support on FireWire ®  Combine usage online and customize the system as needed.

General options: including onboard encoder multiplier, three-axis position synchronous output (PSO), brake relay, additional I/O, absolute encoder interface, and independent logic power input for "keep alive" operation.

Power input: HP, HL, CP, and CL models accept AC input power, while MP models accept DC input power.

Special model: HL is a linear power amplifier suitable for low noise and ultra-high performance applications, meeting high bandwidth requirements, with excellent linearity and no cross distortion; CP is a high-performance PWM amplifier designed for cost sensitive applications; CL is a high-performance linear amplifier designed for cost sensitive applications, while CP and CL retain complex control architectures but eliminate support for optional features; MP is the smallest amplifier in the series, suitable for applications with ultra compact space requirements.
