This example illustrates the default operation of the drive. The example is given to further
illustrate the use of the analog calculations. The full range of the analog input signal corresponds
to the full forward frequency range of the AC drive.
• Minimum Frequency Reference = 0Hz
• Maximum Frequency Reference = 60 Hz
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
A) Drive Maximum Output Frequency = P0.04 = (1750 rpm / 1750 rpm) x 60Hz = 60Hz
B) Analog Offset % = ( 0Hz / 60Hz ) x 100 = 0%

AIx Bias Parameter
C) Analog Gain % = [(60Hz - 0Hz) / 60Hz] x 100 = 100% = AIx Input Gain
