4.4.4. nciSndHrtBt
(Send Heartbeat Time)
SNVT type: SNVT_time_sec (107)
It defines the maximum period of time that expires before the network variables specified for heartbeat
in some monitor values will automatically be updated. This timer restarts to count just after sending
network variables. Refer to “5.4:Communication health management” for details.
- Valid range: 0.0 to 6553.4 sec.
- Unit: 0.1s
- Default value: 0.0 sec.
A value of 0.0sec disables the automatic update.
4.4.5. nciMinOutTm
(Minimum Send Time)
SNVT type: SNVT_time_sec (107)
It defines the minimum period of time between automatic network variable transmissions. This function
is prior to “nciSndHrtBt”. This timer starts to count just after sending the last variable. Refer to
“5.4:Communication health management” for details.
- Valid range: 0.0 to 6553.4 sec.
- Unit: 0.1s
- Default value: 0.5 sec.
Setting 0.0sec disables transmission limitation.
4.4.6. nciMaxSpeed
(
Maximum Speed
)
SNVT type: SNVT_lev_percent (81)
It is used to define the maximum speed of the inverter output. The value is entered as a percentage of
nominal frequency (nciNmlFreq). The value of the maximum speed must be validated against the value
of the minimum speed as follows:
- Valid range: 0.000 %
≤
minimum speed
≤
maximum speed
≤
100.000 %
(Limited within the value of the inverter parameter “
ul
” limitation)
- Unit: 0.005% (the resolution is depends on the inverter’s specification)
- Default Value: 100.000%
N.B.: After resetting the option, it updates the inverter parameter “
ul
”.
Danger
Do not set the value out of valid range.
Setting the value out of valid range may result in injuries by motor running
with unexpected speed.
