Stepper Drives

Liberty Motion Module (LMM) is a programmable motion controller with powerful H-bridge driver. LMM delivers the ultra-compact size and flexibility of a chipset, but with the power and features of leading Liberty MDrive integrated motors, including MCode programming language. The LMM is available in programmable motion control and CANopen control types. Single or four-axis development boards are available to facilitate rapid prototyping, with a Developers Kit recommended with first purchase.

Stepnet Plus TEL is a high-performance DC powered microstepping drive for control of hybrid stepping motors via EtherCAT using the CAN Application protocol for EtherCAT (CoE). Microstepping modes are Profile Position, Interpolated Position Mode (PVT), and Homing. With encoder feedback, the TEL can operate a stepper as a brushless servo motor, enabling Cyclic Sync Position/Velocity/ Torque operation.

As well as operating on EtherCAT networks, the TEL also supports the following traditional control modes: step/direction, RS-232 ASCII, master encoder for gearing and camming, digital input commands to initiate predetermined motion sequences.

Drive commissioning is fast and simple using CME 2™ software operating under Windows® and communicating with the TEL via RS-232 or an EtherCAT network.

Feedback from incremental and absolute encoders is supported. A multi-mode encoder port functions as an input or output depending on the drive’s basic setup. As an input it takes feedback from a secondary encoder to create a dual-loop position control system or as a master encoder for driving a cam table.

Parker Compumotor’s E-DC microstepping drive is designed for a 48VDC input power requirement and provides current up to 4.8 Amps peak of current to the motor.

Parker Compumotor's E-AC is a low-cost, high-performance, high-reliability microstepping drive in a small package. The design of the E-AC is based on the design of our proven Zeta and OEM750 microstepping drives. It provides up to 3.5 Amps of current to the motor and accepts 120VAC direct-online power only. All step motors are subject to mid-range instability or oscillations. The E-AC incorporates an anti-resonance circuitry that aggressively and effectively suppresses these oscillations, thus taking advantage of the full capabilities of the step motor

The Schneider Electric Motion USA stepper motor drive system is comprised of an MForce stepper motor drive and a 2-phase stepper motor for a very compact, high-performance drive system.

The SPiiPlus SDMnt line of multi-axis open loop step motor drives modules are specifically designed to address the needs for economical solutions for machines with many open loop step motors operating as part of an EtherCAT network. It is fully supported by any of ACS’ EtherCAT master controllers, such as the SPiiPlusNT, SPiiPlusNTM and SPiiPlusSC soft Controller.

Stepnet AC is a compact, AC powered microstepping drive for control of hybrid stepping motors. It operates as a stand-alone driver taking Pulse/Direction or CW/CCW inputs from an external controller or as a distributed drive on a CANopen control network. In Servo mode a stepper with encoder operates as a brushless servo motor in position, velocity, or torque modes.
