Robust Liberty MDrive® Pulse /Direction products integrate 1.8° 2-phase stepper motors with onboard control electronics and hMT closed loop performance. Products have 4 modes of operation: pulse/direction input, variable speed control, constant velocity drive, and variable torque control.

Robust Liberty MDrive (LMD) linear motion products integrate either a NEMA 17 or NEMA 23 stepper motor with external shaft linear actuator or captive shaft electric cylinder. Linear motion is produced by ACME screw/nut systems mounted to a motor’s driving shaft. Products include onboard drive electronics and controller with up to 8 I/O. Feedback options include open loop or closed loop with a 1000 line (4000 count/rev) internal incremental or multi-turn absolute encoder with hMT closed loop performance.

This high degree of integration can reduce machine complexity, size and cost in many stepper and servo motor applications. Liberty MDrive delivers exceptional performance and smoothness with advanced current control. Ideal for machine builders who want an optimized motor with onboard electronics.

Robust Liberty MDrive® Motion Control products integrate 1.8° 2-phase stepper motors with control electronics. Included are on-board programmable motion controller for stand-alone operation, and optional hMT closed loop performance.

The Liberty MDrive Ethernet is an integrated NEMA 23 (57 mm) high torque 1.8° stepper motor integrated with an advanced, high resolution microstepping driver and Ethernet controller with multi-protocol support and numerous enhanced features for an Industrial Ethernet or Motion Control solution.

The Liberty MDrive CANopen is an integrated NEMA 23 (57 mm) high torque 1.8° stepper motor integrated with an advanced, high resolution microstepping driver and a full featured CANopen interface supporting CiA DS301: CANopen Application Layer and Communication Profile and DSP402: Device Profile for Drives and Motion Control.

Liberty MDrive CANopen benefits

CANopen is a CAN based higher level protocol used in applications such as automotive, medical equipment, packaging, maritime electronics and railways. Some of the advantages of a CANopen network are: Designed for distributed control Lower cost, simple two-wire interface Interoperability of different devices with standardized device profiles Open, vendor independant protocol with standarization (EN50325-4)

MDrive® Plus Ethernet products integrate 1.8° 2-phase stepper motor, motion controller, drive electronics and optional encoder. MDrive products are EtherNet/IP adapter class devices capable of explicit or implicit messaging. ODVA compliance also enables standardized interface with many other manufacturer systems. ModbusTCP protocol is also supported, operating in immediate mode, not programmable products. Communication may also be via MCode/TCP, a version of the MCode instruction set used for RS422/ 485 serial communication products, adapted to utilize TCP/IP message formatting.

The MDrive® Plus with step /direction input is a 1.8° 2-phase stepper motor with on-board control electronics. Step/direction signals of a master controller, e.g. a motion controller, or A/B signals of an encoder are converted directly into motion.

Settings for MDrive Plus step / direction input products may be changed on-the-fly or downloaded and stored in nonvolatile memory using the SPI Motor Interface software provided. This eliminates the need for external switches or resistors. Parameters are changed via an SPI port.

MDrive® Plus Motion Control products integrate 1.8° 2-phase stepper motor, fully programmable motion controller, drive electronics and optional encoder. Products with encoders include stall detection, position maintenance, and find index mark. Programming for these stand-alone motion control solutions is via RS-422/485 interface with MCode software using simple 1 to 2 character instructions. ModbusTCP protocol is also available.

MDrive® Plus Speed Control products integrate 1.8° 2-phase stepper motor, programmable velocity control, drive electronics and optional encoder. Programmable velocity control uses voltage, current, or PWM analog input signal modes.

Product settings may be changed on-the-fly, or downloaded and stored in nonvolatile memory using the SPI Motor Interface software provided. This eliminates the need for external switches or resistors. Parameters are changed via an SPI port.
