Level 3
Index:
P0773[0] : Analog output 1 (DAC 1) P0773[1] : Analog output 2 (DAC 2)
Dependency:
P0773=0: Deactivates filter.
R0774[2] Act. DAC value [V] or [mA]
Shows value of analog output in [V] or [mA] after filtering and scaling.
Unit: - Min: - Def: - Max: -
Level 3
Index:
r0774[0] : Analog output 1 (DAC 1) r0774[1] : Analog output 2 (DAC 2)
P0776 Type of DAC
Defines type of analog output.
Unit: - Min: 0 Def: 1 Max: 1
Level 3
Settings:
0 Current output
1 Voltage output
Note:
The analog output is designed as a current output with a range of 0...20 mA.
For the ECB variant, the two analog output channels must be of the same type i.e. both channels are current outputs
with a range of 0...20 mA or both channels are defined as voltage outputs with a range of 0...10 V.
P0777[2] Value x1 of DAC scaling
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:
