5.1.2.7 Speed control with two operating ranges
Operation with Speed Sensor 2 at low torsional frequencies enables higher amplification of the speed
controller for large inert tools.
In order to enable better adjustment of the properties of the speed controller at different speeds, it
can be divided in two operating ranges with different amplifications and integral times, independent of
the set actual speed source (see Chapter 5.1.2.5 "Actual speed source"):
− Amplification1/Integral Time1
− Amplification2/Integral Time2
The speed control changeover takes place at the torsional frequency set in Parameter
738.
