Byte 2 Field Current Set Point (LSB) – If Regulation Mode is Field Current Regulation, this
value represents the Least Significant Byte of the field current set point from 0.000-
3.000 A. (1 bit = 1mA)
Byte 3 Field Current Set Point (LSB) – If Regulation Mode is Field Current Regulation, this
value represents the Most Significant Byte of the field current set point from 0.000-
3.000 A. (1 bit = 1mA)
Byte 4 Regulator Voltage Set Point (LSB) – If Regulation Mode is Automatic Voltage Regula-
tion (3 or 1), this value represents the Least Significant Byte of the regulator voltage
set point from 100.0-600.0 V. (1 bit = 0.1 V)
Byte 5 Regulator Voltage Set Point (MSB) – If Regulation Mode is Automatic Voltage Regu-
lation (3 or 1), this value represents the Most Significant Byte of the regulator volt-
age set point from 100.0-600.0 V. (1 bit = 0.1 V)
