Example 1: Standard Operation
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
Calculations
A) Max Output Frequency = (1750 rpm / 1750 rpm) x 60 Hz = 60 Hz
B) Analog Offset % = (0Hz / 60 Hz) x 100 = 0%
C) Analog Gain % = ((60 Hz – 0Hz) / 60 Hz) x 100 = 100%
D) Mid-point Frequency = ((60 Hz – 0Hz) / 2) + 0Hz = 30 Hz
Parameter Settings
P4.01: 00 (default) – Offset disabled
P4.02: 00 (default) – 0% Analog Input Offset
P4.03: 100 (default) – 100% Analog Input Gain
P4.04: 00 (default) – Forward Motion Only
