analog inPut ParaMeter exaMPle 2:
standard oPeration with increased MaxiMuM outPut Frequency
This example illustrates how to run the motor faster than its base speed. For this purpose, the
only required parameter change is P0.04, Drive Maximum Output Frequency. (Motors produce
reduced output torque when running above their base speed.)
WARNING: The dRIve MAxIMuM OuTpuT FRequeNcy pARAMeTeR (p0.04) shOuld NeveR exceed The MAxIMuM

The analog input adjustment parameters can remain defaulted, as determined by the analog input
calculations shown below. The increased Drive Maximum Output Frequency can be obtained
regardless of whether the Source of Frequency Command (P4.00 of P4.01) is an analog input or
one of the other sources, such as the keypad, RS-485 communication interface, jog, or multi-speed
settings.
• Minimum Frequency Reference = 0Hz
• Maximum Frequency Reference = 70Hz
• Motor Maximum Output Speed = 2042 rpm
For AI1, AI2, and AI3: P4.24 (AI V/Hz Calculated Selection) MUST BE SET TO ZERO (All Inputs
Use Bias and Gain) TO ENABLE BIAS AND GAIN CALCULATIONS.
Calculations (see page 4–112 for formulas)
A) Drive Maximum Output Frequency = P0.04 = (2042 rpm / 1750 rpm) x 60Hz = 70Hz
B) Analog Offset % = [0Hz / (70Hz)] x 100 = 0%
