Pocket motion controller
The DMC-30017 motion controller combines a single-axis motion controller and a 6A microstepping drive for operating a two-phase bipolar stepper motor.
Galil Motion Control announced a stepper motor drive option for their DMC-30000 Pocket Motion Controller Series. The DMC-30017 combines a single-axis motion controller with a 6A microstepping drive.
The DMC-30017 contains a microstepping drive for operating a two-phase bipolar stepper motor. The drive produces 256 microsteps per full step or 1024 steps per full cycle which results in 51,200 steps/rev for a standard 200-step motor. The maximum step rate generated by the controller is 3,000,000 microsteps/second. The DMC-30017 drives motors operating at up to 6 Amps at 20 to 80 VDC. There are four software-selectable current settings: 0.75A, 1.5A, 3 A, and 6A.
Designed for compact size, the dimensions of the DMC-30017 controller/drive package are 3.9 in.” x 5.0 in.” x 1.5 in.” and no external heat sink is required.
Other features of DMC-30000 controllers include PID compensation with velocity and acceleration feedforward, non-volatile memory for user programs, multitasking for simultaneously running up to four programs, and I/O processing for synchronizing motion with external events. Modes of motion include point-to-point positioning, position tracking, jogging, contouring, electronic gearing, ECAM, and PVT.
The DMC-30000 provides optically isolated inputs and outputs as a standard feature. I/O include forward and reverse limit inputs, homing input, 8 uncommitted digital inputs, 4 uncommitted digital outputs, 2 uncommitted analog inputs and 1 uncommitted analog output. Two daisy-chainable Ethernet ports are included and an external Ethernet hub is not required. A 115 kb RS232 port is also provided.
In addition to the DMC-30012 controller/servo drive and DMC-30017 controller/stepper drive packages, the DMC-30000 Series is also available as a controller-only model which can be connected to a stepper or servo motor amplifier of any power range.
