• nvoDrvPwr
NOTE
Please note that writing to Configuration
properties will be stored in the Non-Volatile
memory.
Continous writing to Configuration properties
may damage the Non-Volatile memory.
Please note that nciNmlFreq and nciNmlSpeed
can only be written to when the VLT frequency
converter is stopped.
VLT 5000 parameters are shown in parenthesis, where applicable.
