Ndrive ML High-Performance Linear Digital Drive
Not recommended for new designs. See the new Automation1 XL2e. The Ndrive® family of digital servo amplifiers are high-performance discrete drives used with the A3200 motion controller. These drives are capable of controlling brushless, DC brush and stepper motors over a wide range of operating voltages and currents. The Ndrive ML is ideal for low-power, high precision systems.

Description
Design Features
- Output power of 10 A peak
- DC input
- CE approved, NRTL safety certification, EU 2015/863 RoHS 3 directive
- 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
Based on a common architecture, Ndrive amplifiers perform both current- and position-loop closures digitally.
The use of high-performance double-precision processors allows these drives to generate ultra-smooth motion profiles. Servo system response is optimized with the use of up to eight second-order loop-shaping filters, precise time-aligned feed-forward and other proprietary techniques with loop closure rates up to 20 kHz.
The Ndrive family includes several versions of low noise, ultra-high-performance linear drives. The Ndrive series provides high bandwidth and superb linearity required for the ultimate in velocity regulation as well as positional stability. The Ndrive HLe offers the ability to use resolver or inductosyn sensors and provides the highest level of encoder interpolation. For low-power, high precision systems use the Ndrive ML.
Options for the Ndrive family include integral encoder interpolation, one- to three-axis position synchronized output (PSO), automatic brake control, digital and analog I/O expansion, absolute encoder interface, and one- or two-channel resolver interfaces. An optional dedicated ethernet port is available on the HLe drives for connection to third-party I/O expansion devices. This provides the potential to connect to a large number of I/O points typically required for PLC-type applications.
Any combination of Ndrive amplifiers may be connected to the Automation 3200 FireWire® network, allowing the system to be customized as needed.
