NOTES!
When E04 message is displayed (Soft-Starter overtemperature), wait
a few minutes for it to cool down before it can be reset.
When E05 message is displayed (motor overload) or E32 (motor over-
temperature), wait a few minutes for the motor to cool down slightly
before the Soft-Starter can be reset.

DESCRIPTION OF THE ACTUATION
When the value of the active power is higher
than the programmed value, longer than the
programmed time. Referenced to the nominal
motor power.
Itveriestheexistenceofausersoftware.
When forced by the user software.
When forced by the user software.
POSSIBLECAUSES
The percentage value programmed as maximum
acceptable Overpower limit (P662) is below the
necessary for the motor and the application. Tran-
sitory excess of load at the motor. Locked motor,
blocked rotor.
P950=1withoutSoftPLC.
