April 11, 2012 - Galil Motion Control announced DMC-30017, which 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” x 5.0” x 1.5”, and no external heat sink is required. Like other products in the DMC-30000 series, the DMC-30017 is higher speed than Galil’s prior generation single-axis controllers; The 125 microsecond servo loop update time is twice as fast and the 15MHz encoder frequency and 3 MHz stepper pulse output are 25% faster.
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. The DMC-30017 controller and microstepping drive unit is $745 U.S. in single quantity and $480 in quantities of 100.
The DMC-30017 is available for immediate delivery.
