DMC-C640 Ethernet motion controller is designed by Galil and POWERLAND. It’s manufactured in China with full-featured, cost-effective characters. DMC-C640 provides two kinds of communication interface: one RS232 and two Ethernet 10/100 Base-T. The controller is available in one through four-axis formats, and each axis is user-configurable for stepper or servo motor operation. Modes of motion include point-to-point positioning, linear and circular interpolation, electronic gearing, contouring, ECAM, gantry, PVT and so on. Except the forward/reversed limits and home, standard DMC-C640 also provides 8 user defined inputs and 8 user defined outputs. Advanced DMC-C640A can provide up to 32 uncommitted inputs and 32 uncommitted outputs, also including 2 analog (12-bit) inputs and 2 analog (12-bit) outputs. In addition, the controller has two new functions: PWM and absolutely motor control. Like all Galil controllers, programming the DMC-C640 is simplified with two-letter, intuitive commands and Terminal software for tuning, programming.
Program development using many environments such as VB，VC, C#, C++Bulider, Linux etc. DMC-C640 also provides non-volatile memory for storing application programs, parameters, arrays and firmware. Except working independently, the controller also be interfaced with other controllers or HMI to meet different application.
