The following diagram shows conversion values for 1/6,000 resolution.
Analog Output Signal
Ranges
−
10 to 10 V Outputs
When the resolution is set to 1/6,000, the hexadecimal values F448 to 0BB8
(
−
3,000 to 3,000) correspond to an analog voltage range of
−
10 to 10 V.
When the resolution is set to 1/12,000, the hexadecimal values E890 to 1770
(
−
6,000 to 6,000) correspond to an analog voltage range of
−
10 to 10 V. The
entire output range is
−
11 to 11 V.
Specify a negative voltage as a two’s complement.
The following diagram shows conversion values for 1/6,000 resolution.
0 to 10 V Outputs
When the resolution is set to 1/6,000, the hexadecimal values 0000 to 1770 (0
to 6,000) correspond to an analog voltage range of 0 to 10 V.
When the resolution is set to 1/12,000, the hexadecimal values 0000 to 2EE0
(0 to 12,000) correspond to an analog voltage range of 0 to 10 V. The entire
output range is
−
0.5 to 10.5 V.
Specify a negative voltage as a two’s complement.
