P06 Motor (No-load current)
P07 Motor (%R1)
P08 Motor (%X)
These function codes specify no-load current, %R1, and %X. Obtain the appropriate values from the
test report of the motor or by calling the manufacturer of the motor. By performing auto tuning, these
parameters are automatically set as well.
