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 for referencing: 70 kHz 5) The quality of the data cable between EIB and PC must be adapted to the transmission rate and cable length. |
