Possibles Causes
Keypad cable misconnected.
Electrical noise in
installation (electromagnetic
interference).
The time programmed for the
acceleration ramp is shorter than
the actual acceleration time.
Load on the motor shaft too high
Too much successive starts.
Short-circuit between phases.
Motor shaft is locked.
Network phase sequence
inverted at the input.
Electronics supply lower than the
required one.
SSW-05 is defective.
The time programmed for the
acceleration ramp is shorter than
the actual acceleration time.
Short-circuit between phases.
Motor shaft is locked.
The line frequency is out of ran-
ge (+/- 10%), when compared
with the rated frequency (50Hz
or 60Hz).
