Chapter 4: AC Drive Parameters
GS1 Series AC Drive User Manual
4–30
Analog Input Offset Mem Addr 0402H(41027)
Range:0.0 to 100% Default Setting: 0.0
This parameter can be set during the operation
• This parameter provides a frequency offset for an analog input.
• Use the equation below to determine the Analog Input Offset. For this equation,
you will need to know the necessary Minimum and Maximum Frequency
References needed for your application.
Note: The result of the Analog Input Offset calculation will also define the Analog Input
Offset Polarity (4-01). A positive answer means you should have a positive offset. A
negative answer means you should have a negative offset.
Analog Input Gain Mem Addr 0403H(41028)
Range: 0.0 to 300.0% Default Setting: 100.0
This parameter can be set during the operation
• This parameter sets the ratio of analog input vs frequency output.
• 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.
Analog Input Reverse Motion Enable Mem Addr 0404H(41029)
Range: 0 Forward Motion Only Default Setting: 0
1 Reverse Motion Enable
•4-01 to 4-04 are used when the source of frequency command is the analog signal
(0 to +10VDC, 4 to 20mA, or 0 to 10mA). Refer to the following examples:
