Dual-Axis Stepping Motor Intelligent Motion Driver/Controller

MCU-2 Controller

A time tested workhorse, the MCU-2 Dual-Axis Stepping Motor Driver/Controller is a rack mountable dual axis integrated stepping motor driver/controller that drives and controls any 2 (two) 4-phase stepping motors with phase currents from 2 to 6 Amps/phase. The MCU-2 performs indexing function without the need of a host computer, but can operate under the control of a host. The MCU-2's internal nonvolatile memory will store and execute a programmed instruction set, or motor positioning can be achieved through manual control using the MCU-2s front panel controls. The bi-level design of the MCU-2's motor driver produces very low levels of radiated electrical noise which is critical during scientific data collection. When the motor is held at position, no currents are interrupted, therefore there are no radiated electromagnetic fields to interfere with measurements.
