OU.02 AO1
Gain,
OU.03 AO1
Bias The Gain and Bias settings provide scaling adjustment of the analog output
voltage. The graphs below illustrate adjustments of OU.02 (AO1 Gain) and
OU.03 (AO1 Bias) percentages and the affect on the analog output voltage
(AO1). The X-axis is the % value of the selected output item and the Y-axis is
the corresponding output voltage (0
– 10 V) at the AO terminal.
Frequency setting example: Using default values of 100% Gain and 0% Bias
and the maximum frequency set at dr.20 (Max Freq) is 60 Hz. When the
output frequency is 30 Hz, the corresponding X-axis value is 50% or 5V
output at AO terminal.
The percent value of the analog output is based on the following equation.
𝐴𝑂1 =
𝐹𝑟𝑒𝑞𝑢𝑒𝑛𝑐𝑦
𝑀𝑎𝑥𝐹𝑟𝑒𝑞
× 𝐴𝑂1 𝐺𝑎𝑖𝑛 + 𝐴𝑂1 𝐵𝑖𝑎𝑠
OU.04 AO1
Filter Set the filter time constant on analog output.
OU.05 A01
Const% If analog output at OU.01 (AO1 Mode) is set to 15 (Constant), the analog
voltage output is dependent on the set parameter values (0
– 100%).
OU.06 AO1
Monitor Monitors analog output value. Displays the maximum output voltage as a
percentage(%) with 10 V as the standard.
