Parameters 17 and 18 are typically set to the nameplate values of the
connected motor.

Parameter 17 in conjunction with Parameter 18 and the addition of DC
Boost Select set by Parameters 9, 48, 49 and 50, determines the drive
output volts-per-hertz slope up to Base Frequency. The value for Base
Frequency must be greater than the Minimum Frequency set by Parameter
16 and Break Frequency set by Parameter 49 as shown on page 2-37.

Parameters 17 and 18 are typically set to the nameplate values of the
connected motor.

Parameter 18 in conjunction with Parameter 17 determines the drive output
volts-per-hertz slope up to Base Frequency unless modified by Parameters
9, 20, 48, 49 and 50. Parameters 9, 48, 49 and 50 may modify the drive
slope at startup, while Parameter 20 will limit the maximum drive voltage
produced as shown on page 2-37.
