EpoCAT FR1000 / FR4000 is a control board for axes in frequency/burst.

The board is compatible with EtherCAT protocol. With a maximum output frequency up to 1MHz for the FR1000 and 4MHz for the FR4000, it is ideal for applications with step motors, and applications with burst piloted brushless motors. The board manages up to 5 axes in frequency, 4 inputs, 2 outputs, 1 DAC of 12 bit and 2 ADC of 12 bit. The board is supplied with all connectors and can be installed on DIN guide. Since it is a compatible slave EtherCAT board, it is possible to use it with any EtherCAT Master like AxesBrain, LinuxCNC, CODESYS or other.
