Analog Output Specifications
The 1394 SERCOS interface drive includes two analog outputs that can
be configured through software to represent drive variables. Figure
2.11 shows the configuration of the analog outputs. The table below
provides a description of the analog outputs.
Note: Refer to Analog Output Connector on page 2-7 for connector
pin-outs and figures 2.1 and 2.2 for the connector location.
