The DMC-300xx from Galil Motion Control combines a single axis Ethernet controller and an 800Watt sine drive in a low-cost package. Also available as a controller-only model, the DMC can be connected to a stepper or servo motor amplifier of any power range.
Its 32-bit RISC processor provides higher speed and efficiency over previous generation Galil 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.
The DMC-30012 model is packaged with an 800W amplifier for driving brushless servo motors at 20-80 VDC, up to 10 Amps continuous and 15 Amps peak. The fully digital transconductance amplifier is a sinusoidally commutated, brushless motor amplifier which minimizes torque ripple
Other features of the DMC-300xx motion controller 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.
The DMC-300xx 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.
The DMC-300xx accepts position feedback from both a main and auxiliary encoder. Quadrature encoder feedback is standard with BiSS and SSI formats available as an option. A 115 kb RS232 port is also provided.
