Active: first confirm

QuickComm.: No

Max:

4000:0

Defines function of the 0 - 20 mA analog output.

Index:

P0771[0] : Analog output 1 (DAC 1)

P0771[1] : Analog output 2 (DAC 2)

Common Settings:

21 CO: Act. frequency (scaled to P2000)

Datatype: U16

Unit: ms

Def:

2

P-Group:

TERMINAL

Active: first confirm

QuickComm.: No

Max:

Level

2

Defines smoothing time [ms] for analog output signal. This parameter enables smoothing for DAC using a PT1 filter.

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 [mA]

 

Min:

-

 

Datatype: Float

Unit: -

Def:

-

 

P-Group: TERMINAL

 

Max:

-

Level

2

Shows value of analog output in [mA] after filtering and scaling.

Index:

r0774[0] : Analog output 1 (DAC 1)

r0774[1] : Analog output 2 (DAC 2)

P0775[2]

Permit absolute value

 

 

Min:

0

 

CStat:

CT

Datatype: U16

Unit: -

Def:

0

 

P-Group:

TERMINAL

Active: first confirm

QuickComm.: No

Max:

1

Level

2

Decides if the absolute value of the analog output is used. If enabled, this parameter will take the absolute value of the value to be outputed. If the value was originally negative then the corresponding bit in R0783 is set, otherwise it is cleared.

Possible Settings:

0OFF

1ON

Index:

P0775[0] : Analog output 1 (DAC 1)

P0775[1] : Analog output 2 (DAC 2)
