Note: The analog output is designed as a current output with a range of 0 to 20 mA. The two analog output channels
must be of the same type, that is, both channels are current outputs with a range of 0 to 20 mA or both channels
are defined as voltage outputs with a range of 0 to 10V.
P0777[2] Value x1 of DAC scaling
Min: -99999.0 Def: 0.0 Max: 99999.0
Level 2
Data: Defines x1 output characteristic in [%]. Scaling block is responsible for adjustment of output value defined in
P0771 (DAC connector input).
Index: P0777[0] : IN000 Analog output 1 (DAC 1) P0777[1] : IN001 Analog output 2 (DAC 2)
Dependency: Affects P2000 to P2003 (referency frequency, voltage, current or torque) depending on which setpoint is to be
generated.
P0778[2] Value y1 of DAC scaling
Min: 0 Def: 0 Max: 20
Level 2
Index: P0778[0] : IN000 Analog output 1 (DAC 1) P0778[1] : IN001 Analog output 2 (DAC 2)
P0779[2] Value x2 of DAC scaling
Min: -99999.0 Def: 100.0 Max: 99999.0
Level 2
Index: P0779[0] : IN000 Analog output 1 (DAC 1) P0779[1] : IN001 Analog output 2 (DAC 2)
Dependency: Affects P2000 to P2003 (referency frequency, voltage, current or torque) depending on which setpoint is to be
generated.
P0780[2] Value y2 of DAC scaling
Min: 0 Def: 20 Max: 20
Level 2
Index: P0780[0] : IN000 Analog output 1 (DAC 1) P0780[1] : IN001 Analog output 2 (DAC 2)
P0781[2] Width of DAC deadband
Min: 0 Def: 0 Max: 20
Level 2
Index: P0781[0] : IN000 Analog output 1 (DAC 1) P0781[1] : IN001 Analog output 2 (DAC 2)
P0809[3] Copy Command Data Set
Min: 0 Def: 0 Max: 2
Level 2
Index: P0809[0] : Copy from CDS P0809[1] : Copy to DDS P0809[2] : Start copy
Note: Start value in index 2 is automatically reset to '0' after execution of function
P0810 BI: CDS bit 0 (Local/Remote)
Min: 0:0 Def: 718:0 Max: 4095:0
Level 2
Note: Bit 1 is also relevant for BICO data set selection.
