Drive Commissioning: Reference Ramp
Programmed Acceleration Rates
The programmed ramp rate implements a speed dependent ramp rate profile. The
acceleration rate depends on the magnitude of the speed reference. The rate of
change of the speed reference is limited to the acceleration rate when the magnitude
of the speed reference is increasing.
Each of the three acceleration ramp rates is active in a particular speed region.
Acceleration rate 1 is active in region 1, Acceleration rate 2 is active in region 2, and
Acceleration rate 3 is active in region 3. The speed magnitude increases as the
reference progresses from region 1 to region 2 to region 3.
Enter values for the three parameters to define the acceleration ramp rates.

Programmed Acceleration Speeds
The programmed ramp rate implements a speed dependent ramp rate profile. The
acceleration rate depends on the magnitude of the speed reference. The rate of
change of the speed reference is limited to the acceleration rate when the magnitude
of the speed reference is increasing.
There are three speed regions which are characterized by unique acceleration ramp
rates. Region 1 is defined for speed magnitudes less than Accel break point 1. Region
2 is defined for speed magnitudes between Accel break point 1 and Accel break point
2. Region 3 is defined for speed magnitudes greater than Accel break point 2.
Enter values for the two parameters which set the boundaries of the speed regions.

Programmed Deceleration Rates
The programmed ramp rate implements a speed dependent ramp rate profile. The
deceleration rate depends on the magnitude of the speed reference. The rate of
change of the speed reference is limited to the deceleration rate when the magnitude
of the speed reference is decreasing.
Each of the three deceleration ramp rates is active in a particular speed region.
Deceleration rate 1 is active in region 1, Deceleration rate 2 is active in region 2,
and Deceleration rate 3 is active in region 3. The speed magnitude increases as the
reference progresses from region 1 to region 2 to region 3.
Enter values for the three parameters to define the deceleration ramp rates.
