A4 – SDM-44140 (-D4140)
Description
The SDM-44140 resides inside the DMC-40x0 enclosure and contains four microstepping drives for operating two-
phase bipolar stepper motors. The drives produce 64 microsteps per full step or 256 steps per full cycle which results
in 12,800 steps/rev for a standard 200-step motor. The maximum step rate generated by the controller is 6,000,000
microsteps/second. The SDM-44140 drives motors operating at up to 3 Amps at 12 to 60 VDC (available voltage at
motor is 10% less).There are four softwareselectable current settings: 0.5 A, 1 A, 2 A and 3 A. Plus, a selectable
lowcurrent mode reduces the current by 75% when the motor is not in motion. No external heatsink is required.
