Abstract NSLS2 is standardized on Geo Brick LV Delta Tau 5A motor controller, suitable to drive majority of stepper and servo motors. Standardization allows less spare inventory and common skill set to maintain. However, some applications especially instruments in the space confined endstations require using small, or even miniature motors. The question that we address, what are the options in customizing the 5A unit for driving low current motors, and what are the limitations? In this paper, we present a quantitative comparison of drive currents and performance data collected with Delta Tau PeWin software and external test equipment for a variety of low current steppers and servomotors with and without encoders ranging from 45mA to 250mA. Delta Tau Geo Brick LV comes in different amplifier configurations: a combination of 5A, 1A, and 0.25A amplifiers. While all configurations are tested, research goal is focused on performance and limitations of 5A driver, avoiding using step and direction option with extra hardware. Performance of widely used Newport MFA-PP and MFA-CC also will be discussed.
