The Ndrive family of digital servo amplifiers are the high

performance discrete drive options for the Automation 3200

motion system. Capable of driving brushless and DC brushtype

servomotors, and stepper motors, the Ndrive amplifiers

perform both current loop and servo loop closure to ensure

the highest level of positioning performance and rate

stability.

The Ndrives are built using high performance DSPs,

allowing them to perform complex calculations in real time.

This processing capability allows Ndrives to sample the

digital current loop and servo loop at a rate of 20 kHz. The

Ndrive amplifiers also handle both digital and analog I/O,

laser firing, and encoder multiplication.

In order to provide the capability for increased I/O counts

for PLC-type applications, the Ndrive HP and Ndrive HL

have an optional dedicated Ethernet port to communicate

with I/O modules from third-party vendors.

Standard options for the Ndrive include on-board encoder

multiplication, three-axis position synchronized output

(PSO), brake relay, additional I/O, absolute encoder

interface, and separate logic supply inputs for “keep-alive”

operation. The Ndrive HP, Ndrive HL, Ndrive CP, and

Ndrive CL accept AC input power while the Ndrive MP

accepts DC power input.

The Ndrive HL, a linear power amplifier, is available for

low noise and ultra-high performance applications. This

amplifier is ideal for high bandwidth requirements and

maintains superb linearity with zero crossover distortion.

Also included in the Ndrive family is the Ndrive CP, a high

performance PWM amplifier for cost-sensitive applications,

and the Ndrive CL, which is a high performance linear

amplifier for cost-sensitive applications. The Ndrive CP

and CL maintain the same level of sophisticated control

architecture while eliminating support for optional features.
