2.6.1.1. Overview
An acceleration/deceleration ramp is a function allowing linear variations of the motor speed.
The ramp time is the time the motor takes to reach its max. speed when it starts from zero speed (or the time
the motor takes to reach 0 speed when decelerating).
Two sets of two values to be programmed for the motor start and stop are available. Each set of values
identifies the acceleration time and the deceleration time, and each value set is allocated to the unit of
measure of the basic time. The default value is the first set of two values. When the motor runs at constant
speed, and follows the speed reference generated by the MPPT regulator, a set of two values for
acceleration/deceleration defined by other parameters (acceleration and deceleration after start stage) is
applied.
Two values are allocated to the specific function for the start/end ramp.
The Fire Mode operation features two parameters with acceleration ramp times and deceleration ramp times.
The Ramps menu allows setting the acceleration times and the deceleration times of the available speed
ramps.
The set ramp time corresponds to the time the speed reference takes to reach the max. speed (from 0 rpm)
as an absolute value between min. speed and max. speed of the selected motor (
C028
and
C029
for motor
1, and so on).
The time unit of measure may have the following values:
0
0.01 s
1
0.1 s
2
1 s
3
10 s
The programmable range may be 0s
– 327000s.
