NCI: nciRampUpTm
Format: SNVT_time_sec
Explanation:
This network configuration input sets the acceleration time. The value
specifies the length of time it will take to bring the inverter from stop to
maximum frequency.
Default Value: 10.0 seconds
Default PowerFlex 70/700 Drive Parameter Mapping:
Parameter 140 - [Accel Time]
This can be adjusted using the nviNV_config variable or adapter
Parameter 33 - [RampUpTmParam].
NCI: nciRampDownTm
Format: SNVT_time_sec
Explanation:
This network configuration input sets the deceleration time. The value
specifies the length of time it will take to bring the inverter to a stop when
running at maximum frequency.
Default Value: 10.0 sec
Default PowerFlex 70/700 Drive Parameter Mapping:
Parameter 142 - [Decel Time]
This can be adjusted using the nviNV_config variable or adapter
Parameter 34 - [RampDownTmParam].
NCI: nciDrvSpeedScale
Format: SNVT_lev_percent
Explanation:
This network configuration input sets a default value to nviDrvSpeedScale
on every startup.
Default Value: 0%
Valid Range:
±163%
