P0771[2] CI: DAC Level 2
Defines function of the 0 - 20 mA analog output.
Unit: - Min: 0:0 Def: 21:0 Max: 4000:0
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. DC link voltage (scaled to P2001)
27 CO: Act. output current (scaled to P2002)
Index: P0771[0]: Analog output 1 (DAC 1) P0771[1]: Analog output 2 (DAC 2)
P0773[2] Smooth time DAC
Defines smoothing time [ms] for analog output signal. This parameter enables smoothing for
DAC input using a PT1 filter.
Unit: ms Min: 0 Def: 100 Max: 1000
Level 3
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 [V] or [mA]
Shows value of analog output in [V] or [mA] after filtering and scaling.
Unit: - Min: - Def: - Max: -
Level 3
Index: r0774[0]: Analog output 1 (DAC 1) r0774[1]: Analog output 2 (DAC 2)
P0776 Type of DAC
Defines type of analog output.
Unit: - Min: 0 Def: 1 Max: 1
Level 3
Settings: 0 Current output
1 Voltage output
Note: The analog output is designed as a current output with a range of 0...20 mA
For the ECB variant, the 2 analog output channels must be of the same type i.e. both channels are current outputs with a
range of 0...20 mA or both channels are defined as voltage outputs with a range of DC 0...10 V.
P0777[2] Value x1 of DAC scaling
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:
Unit: % 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]: Analog output 1 (DAC 1) P0777[1]: Analog output 2 (DAC 2)
Dependency: Affects P2000 to P2003 (reference frequency, voltage, current or torque), depending on which setpoint is to be generated.
P0778[2] Value y1 of DAC scaling
Defines y1 of output characteristic.
Unit: - Min: 0 Def: 0 Max: 20
Level 2
