PHASE TUNING
SETUP::PHASE CONTROL::PHASE TUNING
The Tuning function block provides a means of injecting a speed offset or a phase offset in a selected wave form to assist the
tuning of the speed and phase loops. It would be unusual for both tests to be active together.
Parameter Descriptions
ENABLE PHASE
Activates a test function to add a test signal to the position demand (phase offset).
ENABLE SPEED
Activates a test function to add a test signal to the speed demand (speed offset).
REFERENCE TYPE
Type of tuning reference, either square, sine, or triangular wave.
Enumerated Value : Type
SPEED AMPLITUDE
This parameter sets the amplitude of the test signal. The signal is symmetric. (i.e. for an amplitude of 1 % the test signal varies
by +/- 1.0 %). In speed test mode, the unit of this parameter are load speed, in position test mode, the unit is percent of 1 load
revolution.
POSN AMPLITUDE
This parameter sets the amplitude of the test signal. The signal is symmetric. (i.e. for an amplitude of 1 % the test signal varies
by +/- 1.0 %). In speed test mode, the unit of this parameter are load speed, in position test mode, the unit is percent of 1 load
revolution.
