2- or 3-phase AC line input or DC input

CE approval

PWM and linear power stages

Digital current, velocity, and position loops for improved motion stability

Optional integrated encoder multiplier for higher throughput and reduced wiring

Flexible design provides ability to drive brushless and DC brush-type servomotors as well as stepping motors

Encoder or resolver feedback




















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 brush-type 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.

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. 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.

The Ndrive MP is the smallest amplifier in the Ndrive family. With an overall package measuring under two inches wide and six inches in height, the Ndrive MP is ideal for applications with ultra-compact space requirements.

Any combination of Ndrive amplifiers can be used together on the FireWire®; network to allow the system to be customized as needed.
