Cycle parameters
Maximum runout Q450: (mm) Specifies the
maximum amplitude of a sinusoidal unbalance
signal. The signal results from the following error of
the measuring axis and from the spindle revolutions.
Speed Q451: (rpm) The unbalance check starts at a
low rotational speed (e.g. 50 rpm). It is automatically
increased by specified increments (e.g. 25 rpm) until
the defined maximum speed is reached. Spindle
override is not effective.
