Description
8
Ramp Freq
Outputs frequency calculated with Acc/Dec function
as a standard. May vary with actual output
frequency. Outputs 10V.
9
PID Ref
Value
Outputs command value of a PID controller as a
standard. Outputs approximately 6.6V at 100%.
10
PID Fdk
Value
Outputs feedback amount of a PID controller as a
standard. Outputs approximately 6.6V at 100%.
11
PID Output
Outputs the output value of a PID controller as a
standard. Outputs approximately 10V at 100%.
12
Constant
Outputs a fixed amount based on the setting of
OUT-05 (AO1 Const %).
OUT-02 AO1 Gain,
OUT-03 AO1 Bias
OUT-08 AO2 Gain
OUT-09 AO2 Bias
The following example uses a 0-10V output at the AO1 terminal.
The Gain and Bias settings provide scaling adjustment of the analog
outputs. The graphs below illustrate adjustments of OUT-02 (AO1 Gain)
and OUT-03 (AO1 Bias) percentages and the effect on the analog output
(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 AO1 terminal.
Frequency setting example: Using default values of 100% Gain and 0%
Bias and the maximum frequency set at DRV-20 (Max Freq) is 60 Hz.
When the output frequency is 30 Hz, the corresponding X-axis value is
50% or 5V output at AO1 terminal.
The percent value of the analog output is based on the following equation.

OUT-04 AO1 Filter
OUT-10 AO2 Filter
Set filter time constant on the analog outputs.
OUT-05
A01 Const %
OUT-11
AO2 Const %
If analog output at OUT-01 (AO1 Mode) is set to 12 (Constant), a fixed
current output can be set between 0–100% for calibration and other uses.
If analog output at OUT-07 (AO2 Mode) is set to 12 (Constant), a fixed
voltage output can be set between 0 - 100% for calibration and other uses.
OUT-06
AO1 Monitor
OUT-12
AO2 Monitor
Monitors analog output values. Displays the output voltage (or current) as a
percentage (%) with 10V or 20 mA as 100%.
