AEROTECH Ndrive HP 10/20/30 P/N: EDU170

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.

1.1. 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. 

Refer to Figure 1-2 for connector locations.

Functional Diagram  

The standard package includes the bus power supply that operates from 85-250 VAC 

(120  350 VDC). The power supply is included with the standard package for off-line 

operation without the need for an isolation transformer. A soft start circuit is included to 

prevent high inrush currents.
