P0756[2] Type of ADC
Defines type of analog input and also enables analog input monitoring
Unit: - Min: 0
Data: Defines type of analog input and also enables analog input monitoring. To switch over from voltage to current analog
input, it is not sufficient to merely modify parameter P0756. Rather, the DIPs on the terminal board must also be set to
the correct position. The DIP settings are as follows:
- OFF=voltage input (10 V)
- ON =current input (20 mA)
Allocation of DIPs to analog inputs is as follows:
- DIP on left (DIP 1)= analog input 1
- DIP on right (DIP 2)= analog input 2
Settings: 0=Unipolar voltage input (0 to +10 V)
1=Unipolar voltage input with monitoring (0 to 10 V)
2=Unipolar current input (0 to 20 mA)
Index: P0756[0]: Analog input 1 (ADC 1)
Dependency: Function disabled if analog scaling block programmed to output negative setpoints (see P0757 to P0760).
Note: When monitoring is enabled and a dead band defined (P0761), a fault condition will be generated (F0080) if the analog
input voltage falls below 50 % of the dead band voltage
Details: See P0757 to P0760 (ADC scaling)
P0757[2] Value x1 of ADC scaling [V / mA]
Parameters P0757 - P0760 configure the input scaling
Unit: - Min: -50.0
Data: Parameters P0757 - P0760 configure the input scaling where:
• Analog setpoints represent a [%] of the normalized frequency in P2000
• Analog setpoints may be larger than 100 %
• ASP max represents highest analog setpoint (this may be at 10 V)
• ASP min represents lowest analog setpoint (this may be at 0 V)
• Default values provide a scaling of 0 V=0 %, and 10 V=100 %
Index: P0757[0]: Analog input 1 (ADC 1)
P0758[2] Value y1 of ADC scaling
Sets value of Y1 in [%] as described in P0757 (ADC scaling)
Unit: % Min: -99999.9
Index: P0758[0]: Analog input 1 (ADC 1)
Dependency: Affects P2000 to P2003 (reference frequency, voltage, current or torque), depending on which setpoint is to be gener-
ated
P0759[2] Value x2 of ADC scaling [V / mA]
Sets value of X2 as described in P0757 (ADC scaling)
Unit: - Min: -50.0
Index: P0759[0]: Analog input 1 (ADC 1)
P0760[2] Value y2 of ADC scaling
Sets value of Y2 in [%] as described in P0757 (ADC scaling)
Unit: % Min: -99999.9
Index: P0760[0] : Analog input 1 (ADC 1)
Dependency: Affects P2000 to P2003 (reference frequency, voltage, current or torque) depending on which setpoint is to be gener-
ated.
P0761[2] Width of ADC dead band [V / mA]
Defines width of dead band on analog input.
Unit: - Min: 0
Index: P0761[0]: Analog input 1 (ADC 1)
Note: P0761[x]=0: No dead band active.
Dead band starts from 0 V to value of
positive or negative respectively. However, dead band is active in both directions from point of intersection (x axis with
ADC scaling curve), if sign of P0758 and P0760 are opposite.
Fmin (P1080) should be zero when using center zero setup. There is no hysteresis at the end of the dead band
P0771[2] CI: DAC
Defines function of the 0 - 20 mA analog output
Unit: - Min: 0:0
Settings: 21 CO: Act. frequency (scaled to P2000)
24 CO: Act. output frequency (scaled to P2000)
25 CO: Act. output voltage (scaled to P2001)
Index: P0771[0]: Analog output 1 (DAC 1)
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
Index: P0773[0]: Analog output 1 (DAC 1)
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: -
