DETAILED PARAMETER DESCRIPTION
6.3.3 - P02-Time of the
Acceleration
Ramp
If defines the time of the voltage a ramp, as shown in fi-
gure 6.1, provided the Soft-Starter does not enter in
current limitation (P11).
When in current limitation, P02 acts as protection time
against locked rotor.

NOTE!
When motors are run without load or with small loads, the
acceleration time will be shorter than the time
programmed at P02, due to the back-emf generated by the
motor.
6.3.4 - P03 - Voltage
Fall step during
Deceleration
(%UN)
Used in pump applications. See item 6.3.19, it set the
voltage (%UN) that will be applied to the motor
instantaneously when the Soft-Starter receives the
command for deceleration by ramp.
NOTE!
In order to enable this function, P04 must be set by
parameter at time according to Figure 6.2.
