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:

100 %

Output signal (mA)

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.
