7.1.2 StartingbyCurrentLimit 
(P202=1)
1) To start the motor with a current limit you must apply a load to the
motor. No-load tests can be done by voltage ramp;
2) SetP102tothetimerequiredforthestart.Atrstsetshorttimes,
20s to 25s. This time will be used as the blocked rotor time, when
the motor is unable to start;
3) SetP110withCurrentLimitbyconsideringitselectricalinstallation
andensuringsu󰀩cienttorqueforthemotorstart.Initiallyyoucan
set 2x to 3x the nominal motor current (In of the motor).
Figure 7.4 - Starting by constant current limit
NOTES!
1) If the current limit is not reached during the starting, the motor will
reach nominal speed immediately;
2) P401 must be set according to the current of the used motor;
3) AlowCurrentLimitresultsintoolowtorqueforthemotorstart.
Always mantain the motor running after it has been enabled;
4) For loads requiring a higher initial starting torque, you can use the
kick start function, P520, or the current ramp;
5) If errors are detected during the motor start, check all connections
of the Soft-Starter to the power line, the motor connections, the
voltage levels of the power line, the fuses, circuit-breakers and
disconnecting switches.
