The encoder parameters depend on the encoder type.

Encoder type "does not exist" for encoder x means that axis x does not exist or

must not be used. In the PROFIBUS message frame, empty useful data are

transmitted for this axis.

Encoder parameters:

Number of encoder lines [encoder lines/revolution]

Both rotary and linear incremental measuring systems can be used, as the spe-

cific parameters of the measuring system are set in den NC machine data (see

Subsection 10.5.5, page 10-317ff).

Encoder parameters:

Select this radio button if the encoder data are to be transmitted from the

encoder to the ADI4 with a parity bit.

Number of encoder lines [encoder lines/revolution]

Number of useful data bits transmitted by the encoder

The following encoder codes are supported:

The following baudrates are supported:

– 187.5 kbps

The baudrate must be set identically for all SSI encoders. If different baudrates

are set, the baudrate of the SSI encoder with the highest encoder number is
