Acceleration RESET function
This parameter has effect only if S ramps are used. Parameter
P031
enables to reset acceleration when reference
trends change.
Whenever a speed reference trend changes, the motor acceleration is instantly set to zero and the ramp output
reference will be computed considering the preset rounding off (see
Figure 6). The figure shows the instant when deceleration begins; the rounding off value assigned to the speed
reference when the gradient changes is the value set for the deceleration starting stage.
If parameter
P031
is set to [No], acceleration is brought to zero before the speed reference starts decreasing, then
deceleration begins with the preset pattern.

If the control algorithm is VTC or FOC and if it is controlled by setting “Torque” (
C011
for motor 1,
C054
for motor 2, and
C097
for motor 3 respectively), the reference is “ramped“ based on the values set in parameter
P026
(torque increase
ramp time),
P027
(torque decrease ramp time), and
P028
(unit of measure for the ramp times). The ramp up time
setting is the time the output torque reference takes to go from 0 to the max. value (as an absolute value) between
Torque min. and Torque max. of the selected motor (
C047
,
C048
for motor 1 and so on).
