1) The supply voltage range of the encoder must be maintained; specified cable length applies when HEIDENHAIN cables are used. 2) Various trigger sources can be assigned to the individual axes. 3) Can also be used as logical input or output 4) Maximum input frequency during referencing: 70 kHz 5) The quality of the data cable between the EIB and PC must be adapted to the transmission rate and cable length. |
