Eliminated function restriction
At initial speeds of about 0 rpm in connection with low digital frequency resolutions (small numbers of increments), pulses were output at the digital frequency output although the setpoint for the DFOUT_dnSet_s output was zero. The reason for this was an internal setpoint position for the digital frequency output which cannot be displayed in integer increments. So the initial speed is toggling between a very small positive and negative value.
This does not result in the master position drifting with regard to following axes if the output frequency is evaluated using a Lenze device.
In the course of revision this function restriction has been eliminated.
