Output Characteristics (D/A)
On the KV-AN6, the analog output function converts digital (binary) data to analog
external output signals. The digital data stored in data memory is converted to
analog data and sent to an output unit at every scan time.
The analog output signal can be set according to the input range as shown in the
following table.
The selection switches in the table are located on the right side of the KV-AN6.
➮ Refer to page 1-319.

Current output
Through the D/A converter, digital data stored in the assigned data memory ad-
dresses by channel (Refer to page 1-324) is output as analog signals. The effective
bits are the 12 bits starting from the most significant digit.
Note: A change in the value of the DM address from 7FFFH (32767) to 8000H
(32768) or vice versa means that the polarity is reversed when the voltage output is
selected, or that output drastically changes from the maximum value to the minimum
value or vice versa when the current output is selected. Use the program to maintain
output data within the specified range.
