Palm-sized Motion Checker MCH-2 integrates constant voltage driver, intended for tin can-type stepper motors, that is available in bipolar 400 mA rated, 700 mA peak, or unipolar 250 mA rated, 400 mA peak configurations. Using front panel controls, operator can create constant-speed motion or trapezoidal motion with programmable low and high speeds, as well as ramp-up/down times. Suited for field testing and inspection, control lets motion profiles be set to run indefinitely or for set number of times.
