Figure 6.2 - Deceleration Ramp
Used in pump applications. See item 6.3.19.It defines the
time of the deceleration ramp that will be effected at the
level set at P03 up to the thyristor locking voltage which
is approx. 30% of the UN. As shown in Figure 6.2, this
ramp is mainly beneficial for pump application.
NOTE!
This function is used to lengthen the normal load deceleration
time and not to force a time shorter than that imposed by the load.

6.3.6 - P11 - Current
Limitation
(%IN of the
switch)
It sets the max.current value that will be supplied to the
motor (load) during the acceleration.
The current limitation is used for loads with high or
constant starting torque.
The current limitation must be set at a level that permits
the motor acceleration, otherwise the motor will not start.
NOTE!
1) If the full voltage is not reached at the end of the
acceleration ramp time (P02), the error E02 will be
displayed and the motor will be disabled.
P11 - Current limitation
2) The thermal thyristor protection, inclusive during the
current limitation, is carried through thermostats of the
Soft-Starter.
