(1) This area is used to confirm the setting range of the D/A converter module.
Settings for channels 1 to 4 are stored in Un\G20.
Settings for channels 5 to 8 are stored in Un\G21.
(2) For Q62DAN, Q62DA, b8 to b15 (CH3 and 4 information) for Un\G20 and Un\G21
(information of CH5 to CH8) are invalid.
For Q64DAN, Q64DA, Un\G21 (CH5 to CH8 information) is invalid.

(1) Specifies the channel to be adjusted for the offset/gain settings.
(2) Specification can be made for 1 channel only.
An offset/gain setting mode error (error code 500) will occur if more than one
channel is specified at the same time.
(3) For Q62DAN, Q62DA, b2 to b7 (CH3 to CH8) are invalid.
For Q64DAN, Q64DA, b4 to b7 (CH5 to CH8) are invalid.

(1) This area is used to set the amount of adjustment for analog output values in the
offset/gain setting mode.
(2) The valid input range is from –3000 to 3000.
When the input value is 1000, the analog output values can be adjusted by about
0.33 V for voltage output and about 0.65 mA for current output.
(3) See Section 4.6 for the details of the offset/gain settings.
