AEROTECH EDU176_Ndrive_HL
Aerotechs Network Digital Linear Drive (Figure 1-1) (and PWM Ndrive CP, HP, MP,
and Nservo, Npaq) complement the Automation 3200 System. 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 are linear for eliminating
EMI/RFI emissions and have fully digital current and servo loops providing up to an 8
kHz servo loop closure, 32 MHz line driver encoder data rate, and an optional Ethernet
port for access to third party networked I/O solutions. Additionally, one 18 bit analog
output and one 16 bit analog input is standard. The Ndrive HL also features an optional
on-board brake relay, programmable resolution multiplication up to x65.536. 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.
This product is intended for light industrial manufacturing or laboratory use.

Feature Summary
• Software configurable for brush (torque/current and tachometer mode) and
brushless motor operation
• Bipolar 40 or 80 VDC bus power supply
• Fully isolated power stage
• 5 VDC, 500 mA 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 inputs (one standard and one available with the IOPSO option)
The Ndrive HL consists of a power connection (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/-IOPSOH option is also available, shown below (J301
J303. TB301-TB305), which has connections for PSO, absolute encoder, SSI Net, analog
I/O, digital I/O, and user power. Refer to Figure 1-2 for locations.

Ndrive HL Block Diagram
The standard package includes the bus power supply that operates from standard AC line
voltage (100/115/208/230 factory configured). The power supply is included with the
standard package for off-line operation without the need for an isolation transformer.
Figure 1-3 is a functional diagram including options. In addition, a soft start circuit is
included to prevent high inrush currents.
