The optionally available digital frequency extension module serves to extend the L-force
9400 Servo Drive by a digital frequency input and a digital frequency output.

The 32-bit absolute position output by the system block LS_DigitalFrequencyInput at the

Note!
The speed is not affected by setting the position.
If the speed is integrated in the application, the integrator and the position
assume different values, i.e. they diverge. In case of further position changes, the
difference between the values remains the same.

2.2.4 Use of machine parameters for scaling
This function extension is available from software version V3.0 onwards!
The input DFIN_AxisData can be used to transfer the machine parameters of the own
motor/drive or of a higher-level drive to the system block LS_DigitalFrequencyInput.
If valid machine parameters are applied to the input DFIN_AxisData, then the outputs
for the actual position and the actual speed are evaluated on the basis of the
transferred machine parameters (gearbox factors, encoder resolution).
– The position is scaled to the set measuring system/traversing range.
– The encoder mounting position can be parameterised under C13015
If the input DFIN_AxisData remains unused, the system block continues to operate as
before. In this case the units are scaled to revolutions.

2.3 Problem description - speed variations
In the digital frequency extension module rectangular encoder signals are processed. The
speed is determined by counting the edges occurring within a defined time interval (1 ms).
Due to this defined time interval of 1 ms and a finite number of encoder increments per
revolution, the calculated speed signal can only assume discrete values. This gives the
impression that the signal is very unsteady and inexact. This effect increases with lower
numbers of increments.
An example for calculating the expected speed variation can be found in chapter "Digital
frequency output". Problem description - speed variations
