If Vdc Optimize (102) is set to Disabled, Vdc Reference (103) is the minimum
DC bus voltage generated by the rectifier while the rectifier or the entire drive is
running.
If Vdc Optimize (102) is set to Enabled, then Vdc Reference (103) is not used.
Displays the commanded DC bus voltage.
See Vdc Optimize (102) for more information on how the rectifier derives this
command when it or the entire drive is running.
When the rectifier is not running, this parameter matches the DC bus voltage as
measured by the rectifier, visible in DC Bus Voltage (10).
The maximum RMS current the rectifier produces expressed as x.x A.
Sets the 100% current level for the rectifier I2T diagnostic Overload fault
(fault 220).
