Using an Analog Input in Command System Parameters
• When using analog input terminals by the following functions, configure parameters for selecting the
commands of each function in addition to Input Terminal [AI1] Function Selection (3005Hex-3EHex).
When both are set to analog input, analog input signal is treated as a command.

Analog Input Adjustment Function

This function adjusts the offset, bias and gain of the analog input terminals [AI1].
• The analog input terminal [AI1] has a voltage input only.
• Select the polarity (3006Hex-24Hex) of the analog signal to input and set the input range of the ana-
log signal.
• Add the value set at Offset (3006Hex-20Hex) to the analog input value, and adjust for shift of the
offset.
• Set the bias (command) (3004Hex-13Hex/3006Hex-38Hex) and gain (command) (3006Hex-21Hex),
and convert the analog signal to digital value and adjust the resulting signal. Adjust the base point of
bias (command) and gain (command) at bias (analog input) (3006Hex-33Hex/3006Hex-39Hex) and
gain (analog input) (3006Hex-23Hex).
• Filters (3006Hex-22Hex) can be set to remove noise.
