Phase B Current Measurement
Enhanced Mode Data
This is a read-modify-write register, once the drive is set up for enhanced mode, the following procedure
can be followed to access additional information:
 Read the ADC B data register (i.e. query it in the terminal window)
 Set the strobe word to the desired command code of a function (i.e. Reading Bus Voltage)
 Read the lower 12 bits of ADC B to access the reported bus voltage value
Note
Subsequent additional information command code must follow the
same procedure with the drive always in enhanced mode until the next
logic power cycle.
