• Function can be set
The function of the analog input is defined by the interconnection of the numeric signal sink
with parameter r0755.
Multiple interconnections are possible.
Parameter r0755 is assigned to the respective analog input by its index, e.g. parameter
r0755[0] is assigned to analog input 0.
Frequently used numeric signal sinks:
• Offset can be set
Parameter p0763 determines the offset for the analog input.
• Smoothing can be set
Parameter p0753 causes a smoothing of the input signal using a PT1 filter. This allows strong
fluctuations or short-term peaks to be suppressed.
• Noise suppression can be set
Analog values are always subject to noise. Parameter p0768 determines the value of the
noise suppression for the input signal.
• Wire-break monitoring can be set
Parameters p0761 and p0762 define the behavior of wire break monitoring.
• Absolute-value generation can be set
Parameter p0766 represents the amount of the scaled input value.
• Inversion
Binary signal sink c0767 inverts the analog input signal.
• Enable
Binary signal sink c0769 enables the analog input.
• Simulation mode
Parameters p0797 and p0798 simulate the analog input signal.
• Deadband
Deadband p0764 suppresses unwanted signals below an adjustable threshold. This prevents
the converter from reacting to electromagnetic interference at speed setpoints close to 0.
