Aerotech Ndrive HP 10/20/30 Networked Digital Drives

INTRODUCTION

Aerotechs Network Digital Drives (Ndrive HP) complement the Automation

3200 System (see Figure 1-1). Connected via the IEEE-1394 (FireWire®)

communication bus, these drives provide deterministic behavior, auto-

identification, and easy software setup from the Nmotion SMC software

controller. Featuring a high-speed Harvard architecture DSP, the drives

have fully digital current and servo loops providing selectable 1-20 kHz

servo loop closure, 40 MHz line driver encoder data rate, and an optional

Ethernet port for access to third party networked I/O solutions. 

The Ndrive HP also features an optional on-board brake relay, programmable

resolution multiplication up to x 65.536. with a 200 kHz maximum amplified

sine wave input frequency, and up to three-axis Position Synchronized

Outputs (laser firing). In addition, the use of the commercially standard

FireWire communication link makes integration to the Automation 3200

network plug-n-play easy.

Feature Summary

• Software configurable for brush, brushless and stepper motor operation

• Standard 100 VDC 320 VDC Bus, optional 20 VDC 80 VDC Bus, requires

the -AUXPWR option

• Fully isolated power stage

• 5 VDC, 500 mA fused user output power for encoder and Hall effect signals,

etc.

• Two mounting orientations optimized for heat transfer or minimal panel

space utilization

• Full protection against the following failure modes:

1. Control supply under voltage

2. Continuous current overload

3. Power stage bias supply under-voltage

4. Power stage output short circuit (phase to phase and phase to ground)

5. DC bus over voltage

6. IGBT device over temperature sense

• Line driver square wave or analog sine wave quadrature encoder primary

position and velocity feedback

• Line driver square wave auxiliary quadrature encoder input or output for PSO

(laser firing), etc.

• 4 opto-isolated user outputs standard

• 6 opto-isolated user inputs standard, 2 of which are high speed

• 2 differential analog inputs (one standard and one available with the IOPSO

option)

• 2 analog outputs (one standard and one available with the IOPSO option)

Connection Overview

The Ndrive HP consists of two power connections (motor power and input power),

three FireWire ports, an optional Ethernet connection, an RS-232/RS-422 connector,

LED indicator lamps and two D-Style connectors for Auxiliary I/O (15 and 26 pin)

and Motor Feedback (25 pin). An IOPSO or -IOPSOH option is also available, which

has connectors for PSO, absolute encoder, SSI Net, analog I/O, digital I/O, and

user power.
