Pocket motion controller

A new addition to the DMC-30000 Pocket Motion Controller Series is the DMC-30017. The controller combines a single-axis motion controller with a 6-A microstepping drive for operating a two-phase bipolar stepper motor. The drive produces 256 microsteps/full step or 1,024 steps/full cycle, which results in 51,200 steps/rev for a standard 200-step motor. The controller generates a maximum step rate of 3,000,000 microsteps/sec, and drives motors operating at up to 6 A at 20 to 80 Vdc. There are four software-selectable current settings: 0.75, 1.5, 3, and 6 A.

The unit’s 125-μsec servoloop update time is half that of previous single-axis controllers, and the 15-MHz encoder frequency and 3-MHz stepper pulse output are 25% higher. Additional features include PID compensation with velocity and acceleration feedforward, nonvolatile memory for user programs, multitasking for simultaneously running up to four programs, and I/O processing for synchronizing motion with external events.
