User Manual

Conditions Required for Operation 8-3
8.6 Reading Values from VTAC 7 Registers
The address set in nciRdReg is polled and the result is written to nvoParam as often
as the value on the address changes or the work load on the host application and
nciMinOutTime allows.
8.7 Resetting Faults
If an error occurs, the drive faults. The fault can be reset from the LonWorks module
by first removing the cause of the fault, then setting nviObjRequest to
RQ_CLEAR_ALARM. All drive-related NCIs will be updated with the current drive
value.
8.8 Priority of nciMinOutTm and nciSendHrtBt
NciMinOutTm has priority over nciSendHrtBt. This means that heartbeats will not be
sent as often as specified in nciSendHrtBt if nciMinOutTm has a longer time set.
