Drive Commissioning: Reference Ramp
Programmed Acceler ation Rates
The programmed ramp rate implements a speed dependent ramp rate profile. The
acceleration rat e depends on the magnitude of the speed r eference. The rate of
change of the speed referen ce is limited to the accelerat ion rate when the magnitude
of the speed reference i s increasing.
Each of the three acceler ation ramp rates is active in a part icular 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 a s the
reference progresses from region 1 to region 2 to region 3.
Enter values for the thr ee parameters to define the acceler ation ramp rates.

Programmed Acceler ation Speeds
The programmed ramp rate implements a speed dependent ramp rate profile. The
acceleration rat e depends on the magnitude of the speed r eference. The rate of
change of the speed referen ce is limited to the accelerat ion rate when the magnitude
of the speed reference i s increasing.
There are three speed r egions which are characterized by un ique 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 parameter s which set the boundaries of the speed regions.

Programmed Deceler ation Rates
The programmed ramp rate implements a speed dependent ramp rate profile. The
deceleration rate d epends on the magnitude of the speed refer ence. The rate of
change of the speed referen ce is limited to the decelerati on rate when the magnitude
of the speed reference i s decreasing.
Each of the thr ee deceleration ramp ra tes is active in a par ticular speed regi on.
Deceleration rate 1 is active in region 1, Deceleration rate 2 is active in region 2,
and Deceleratio n 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 thr ee parameters to define the deceler ation ramp rates.
