Changing Output Characteristics

For FX -4DA, the standard output characteristics are provided for each output mode (BFM#0)at the time of
3U
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.
