Network config input SNVT_time_sec
nciRcvHrtBt
Description
The ‘nciRcvHrtBt’ variable is used to configure the maximum update interval for the network input variables
‘nviDrvSpeedStpt’ and ‘nviDrvSpdScale’. If the ‘nviDrvSpeedStpt’ and ‘nviDrvSpdScale’ variables are not updated for
the set time (‘nciRcvHrBt’ time value + PRT-13 Lost Cmd Time), the inverter decides that the command is lost. It then
runs in the operation mode set by thePRT-12 Lost Cmd Mode.
Lost command time protection operates only when the ‘nciRcvHrtBt’ variable is set to a value other than 0.0 sec,
DRV-06 Cmd Source or DRV-07 Freq Ref Src is set to ‘Fieldbus’, and PRT-12 Lost Cmd Mode is set to any other value
than ‘None’.
The lost command protection feature is disabled if the ‘nciRcvHrBt’ variable is set to 0.0 sec.
Typical Range
0.0 – 120.0 sec (0.1 sec increments)
A value of 0xFFFF(6553.5 sec) is invalid data.
Default
0.0 sec (Receive Heart Beat feature is disabled)
