Modes

The D/A converter module has the high-speed output mode, normal output mode, wave output mode, inter-module
synchronization mode, and offset/gain setting mode. Change the operation mode according to the function used.
High-speed output mode
This operation mode is for performing the high-speed D/A conversion. The value set in 'CH1 Digital value' (Un\G460) is output
in analog after the D/A conversion. Conversion speed is 1s/CH.
Program CH
Normal output mode
This operation mode is for performing the normal D/A conversion. The value set in 'CH1 Digital value' (Un\G460) is output in
analog after the D/A conversion. Conversion speed is 10s/CH.
Program CH
