FX3U-4DA (4-channel Analog Output)
7. Changing Output Characteristic
For FX3U-4DA, the standard output characteristics are provided for each output mode (BFM #0)at the time of
factory shipment.
Changing the offset data (BFM #10 to #13) and gain data (BFM #14 to #17) can change the output
characteristics of each channel. This chapter describes how to change the output characteristics.
7.1 Procedure for Changing Output Characteristics
1 Cancel the setting change prohibition mode.
If setting change is prohibited, write K3030 in BFM #19. The setting change prohibition mode will
be canceled.
2 Determine the output mode (BFM #0).
Determine the output mode (BFM #0) optimum for the selected channels and the voltage/current
specifications.
Example: Enter "HFF00" in BFM to set output mode 0 for channels 1 and 2 and prevent use chan-
nels 3 and 4
Cautions regarding data setting
• If a value "1" or "4" is set for a channel, the output characteristics of the channel cannot be changed.
• Set the optimum output mode for the analog signal to be output.
Set value (HEX) Output mode Analog output range Digital input range
0 Voltage output mode -10V to +10V -32000 to +32000
1
Voltage output analog value mV
specification mode
The characteristic cannot be changed.
2 Current output mode 0mA to 20mA 0 to 32000
3 Current output mode 4mA to 20mA 0 to 32000
4
Current output analog value μA
specification mode
The characteristic cannot be changed.
