BONFIGLIOLI Active Cube Applications Manual

5.1.2.6 Speed sensor monitoring
In order to synchronize the machine orientation with the reference pulse, the speed sensor monitoring
operation mode
Operation Mode 760 must be set to “2 – Error” (default value).
In this setting, a wrong number of division marks is reported automatically and individual missing
division marks are corrected using the reference pulse.
Monitoring is turned off above the
Frequency Limit 624.

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
Speed Control
Switch-Over Limit
738.
• The value set in Parameter
Speed Control Switch-Over Limit 738 should be at least 10% smaller
than the
Frequency Limit 624.
• Optimize
Amplification 1 721 and Integral Time 1 722 for operation with speed controller.
• Optimize
Amplification 2 723 and Integral Time 2 724 for sensor-less operation.
