Chapter 4: AC Drive Parameters
4–44
2nd Analog Input Gain
Default Setting: 100.0
Range: 0.0 to 300.0%
This parameter sets the ratio of the second analog input vs frequency output.
• Select the 1st or 2nd sources with a Digital Input and the appropriate parameter
settings for P3.02 through P3.10.
• Use the equation below to calculate the Analog Input Gain. For this equation, you
will need to know the minimum and maximum set-point frequencies needed for
your application.
• This parameter is available only with AC drive firmware v1.04 or higher.
Refer to P9.39 to determine the drive’s firmware version.
Trim Reference Frequency
Default Setting: 00
Range: 0.0 to 400.0 Hz
This parameter determines a set frequency to add to or subtract from the selected
Frequency Command (P4.00 or P4.13) to produce a modified actual frequency
command. The setting of P4.18 determines whether P4.17 adds to or subtracts
from the Frequency Command.
• This parameter is active only if P4.18 is set to 03 or 04.
• This parameter is available only with AC drive firmware v1.04 or higher.
Refer to P9.39 to determine the drive’s firmware version.
