Powerful CNC controller
up to 6 axes
The main task of a CNC controller is to generate clock and direction signals for stepper motors, as this is not possible in real time under Windows. Depending on the controller, the step frequency is up to 300 kHz for interpolated movements of up to 6 axes.
Our CNC controllers have several protected digital inputs and outputs (opto-isolated) as well as analogue inputs and outputs. Optoisolators ensure electrical isolation between input and output signals and thus protect against voltage peaks and electromagnetic interference. This contributes to the reliability and longevity of the CNC controller and the connected devices.
Signals for reference switches, start/stop signals and other switching states are recorded at dedicated inputs. Additional outputs enable the control of further hardware and functions, such as a current reduction, switching coolant pumps or the spindle on and off. The spindle speed can be controlled in 255 steps.
Our CNC controllers allow the connection of an electronic handwheel for direct machine control. They also support a dual drive for the X/X2 or Y/Y2 axes.
