3.12 Analog outputs
r0770 Number of DACs Min: -
Datatype: U16 Unit: - Def: -
P-Group: TERMINAL Max: -
Displays number of analog outputs available.
P0771[2] CI: DAC Min: 0:0
CStat: CUT Datatype: U32 Unit: - Def: 21:0
P-Group: TERMINAL 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)
24 CO: Act. output frequency (scaled to P2000)
25 CO: Act. output voltage (scaled to P2001)
26 CO: Act. filtered DC-link volt. (scaled to P2001)

P0773[2] Smooth time DAC Min: 0
CStat: CUT Datatype: U16 Unit: ms Def: 2
P-Group: TERMINAL Active: first confirm QuickComm.: No Max: 1000
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: -
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
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:
0 OFF
1 ON
Index:
