2 μs
... provides a binary output signal which is generated by the logic
combination of five input signals.
3 μs
...differentiates signals. The function block can, for instance, be used to
apply an acceleration (dv/dt).
2 μs
... outputs one of 16 parameterisable analog signals.
2 μs
... outputs one of 16 parameterisable data words.
3 μs
... can amplify an analog input signal and then add an offset to it.
• Gain and offset can be set via FB inputs.
3 μs
... can amplify an analog input signal and then add an offset to it.
• Gain and offset can be set via parameters.
3 μs
... can amplify an angle signal and then add an offset to it.
• Gain and offset can be set via parameters.
3 μs
... compensates elasticities in the drive train (gearbox compensation).
•
This FB is available from version 12.00.00.
5 μs
... can interpolate a position setpoint and/or an analog value e.g. to
compensate for larger bus transmission cycles or to continue signal
characteristics if data telegrams are missing.
5 μs
... can be connected upstream to the
implement a switch-off positioning at limit switch.
3 μs
... limits an analog input signal to an adjustable value range.
3 μs
... limits an angle signal to an adjustable value range.
5 μs
... provides the application with process inputs for controlling various
basic functions of the Motion Control Kernel.
5 μs
... provides the application with various items of status information of
the Motion Control via process outputs.
10 μs
... replaces a hardware motor potentiometer as setpoint source.
4 μs
... multiplies the analog input signal with a factor.
3 μs
... switches one of eight selectable input signals to the output.
2 μs
... negates an analog input signal.
3 μs
... can suppress up to three parameterisable blocking zones within a
continuous signal characteristic of an analog input signal.
2 μs
... inverts a digital input signal.
50 μs
... contains a ramp generator with comprehensive parameterisation and
control options to condition a setpoint signal.
2 μs
... detects positions and calculates distances.
4 μs
... can add an offset to an analog input signal and amplify it afterwards.
• Offset and gain can be set via FB inputs.
