Siemens MICROMASTER 440 - Type of DAC; Value X1 of DAC Scaling

Parameter Description Issue 01/06
MICROMASTER 440 Parameter List
94 6SE6400-5BB00-0BP0
P0776[2] Type of DAC Min: 0
CStat: CT Datatype: U16 Unit: - Def: 0
P-Group: TERMINAL Active: first confirm QuickComm.: No Max: 1
Defines type of analog output.
Possible Settings:
0 Current output
1 Voltage output
Index:
P0776[0] : Analog output 1 (DAC 1)
P0776[1] : Analog output 2 (DAC 2)
Note:
The analog output is designed as a current output with a range of 0...20 mA.
For a voltage output with a range of 0...10 V an external resistor of 500 Ohms has to be connected at the
terminals (12/13 or 26/27).
P0777[2] Value x1 of DAC scaling Min: -99999.0
CStat: CUT Datatype: Float Unit: % Def: 0.0
P-Group: TERMINAL Active: first confirm QuickComm.: No Max: 99999.0
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:

Where:
Points P1 (x1, y1) and P2 (x2, y2) can be chosen freely.
Index:
P0777[0] : Analog output 1 (DAC 1)
P0777[1] : Analog output 2 (DAC 2)
Example:
The default values of the scaling block provides a scaling of:
P1: 0.0 % = 0 mA
P2: 100.0 % = 20 mA
Dependency:
Affects P2000 to P2003 (referency frequency, voltage, current or torque) depending on which setpoint is to
be generated.
