P0776[2] | Type of DAC |
|
| Min: | 0 | |
| CStat: | CT | Datatype: U16 | Unit: - | Def: | 0 |
| TERMINAL | Active: first confirm | QuickComm.: No | Max: | 1 |
Level
2
Defines type of analog output.
Possible Settings:
0Current output
1Voltage 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: | |||
CStat: | CUT | Datatype: Float | Unit: % | Def: | 0.0 |
TERMINAL | Active: first confirm | QuickComm.: No | Max: | 99999.0 |
Level
2
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.
