Par. No. Name Range Default Unit
P0771 DAC 0.0 - 2036.0 24.0 --
Defines function of the 0 - 20 mA analog output.
Possible settings:
0 Analog output current: 0 mA
1 Analog output current: 20 mA
24 Actual output frequency
25 Actual output voltage
26 Actual DC-link voltage
27 Actual output current
37 Actual inverter temperature
P0773 Smooth time DAC 0 - 1,000 2 ms
Defines smoothing time [ms] for analog output signal. This parameter enables smoothing for DAC using a
PT1 filter.
Dependency:
P0773 = 0: Deactivates filter
P0777 Value x1 of DAC scaling -99999 - 99999 0.00 %
Defines x1 output characteristic in [%]. Scaling block is responsible for adjustment of output value defined in
P0771 (DAC connector input).
Parameters of DAC scaling block (P0777 ... P0781) work as follows:
Output signal (mA)

Where:
Points P1 (x1, y1) and P2 (x2, y2) can be chosen freely.
P0778 Value y1 of DAC scaling 0.00 - 20.00 0.00 --
Defines y1 of output characteristic.
P0779 Value x2 of DAC scaling -99999 - 99999 100.00 %
Defines x2 of output characteristic in [%].
P0780 Value y2 of DAC scaling 0.00 - 20.00 20.00 --
Defines y2 of output characteristic.
P0781 Width of DAC deadband 0.00 - 20.00 0.00 --
Sets width of deadband in [mA] for analog output.
