Network Variable Inputs

(NVIs)

This section provides descriptions of the Network Variable Inputs.

Variable: nviObjRequest

Format: SNVT_obj_request

Explanation:

This input enables control commands and updates from the network to
specific objects in the node. The identification number for the node is 0 and
for the drive object is 1. The request functionality is the same for both
objects. The setting of nviObjRequest does not affect the ability of setting
drive speed. The status of the node is reported in nvoObjStatus.

Valid Range for Object ID: 0 or 1

Valid Range for Request:

RQ_UPDATE_STATUS updates nvoObjStatus.

RQ_CLEAR_STATUS clears nvoObjStatus.

RQ_CLEAR_ALARM clears a fault in the drive.

RQ_REPORT_MASK reports supported requests in nvoObjStatus.

RQ_NORMAL and RQ_ENABLE are the normal requests when node
function is normal.

All other requests are not supported, and any attempt to use them sets the
invalid_request bit in nvoObjStatus.
