Mclennan STR-2M Microstepping Motor Drive 0.25 A to 2.2 A/phase 12 to 48VDC

The Mclennan STR-2M is a very compact 2-phase stepper motor drive controlling basic step and direction. It features advanced micro-stepping and anti-resonance current control, damping motor and system resonances electronically. This results in improved torque and smoother motor running. The STR-2M also has Micro-step Emulation to allow micro-stepping when used with low-resolution command pulses. Operation modes are step and direction or pulse/pulse.
