If enabled, this
secondary start protection uses both the basic start
protection and the area under the curve protection.
The maximum I
2
T allowed during
start. If the I
2
T to start exceeds this number then the
soft starter will generate a trip.
Learns the motor’s starting
characteristics and protects the motor based upon
the learned curve. It is useful when commissioning a
new motor.
The unit reads the motor’s starting
characteristics. Start the motor and allow it to come
to full speed. The start feedback enables the motor
protection based on the learned start curve.
The maximum allowed
deviation above or below the start curve before a trip
is generated.
The time the soft starter
continues to sample the start curve characteristic
during learn the mode.

Congures the unit’s start and
run protection mode. The unit has
independent start and run curve
protection and the settings can be
based on the OL Class or set by the
motor’s locked rotor current and time.
SP8.1
: Set the locked rotor time
to the OL Class default chosen
in Setpoint Page 1 or set the
time in seconds. This is the
time the locked rotor condition
exists before a trip occurs.
:
The current the motor draws
with full voltage on the windings
and no rotor movement (as a
percent of motor FLA). Refer to
the nameplate data or contact
the motor manufacturer.
If enabled,
this prevents the motor from
restarting for the programmed
amount of time, after a stop
command is given.
The locked
rotor time can be set to the OL Class default
chosen in Setpoint Page 1 or to a specic
time. The overload condition must exist for the
programmed amount of time before a trip occurs.
The current the
motor draws with full voltage on the windings and
no motor movement (as a percent of motor FLA).
Refer to the motor nameplate data or contact the
motor manufacturer.
: If the motor does not
enter run mode (reach at speed) within the preset
time, the unit trips on acceleration time limit.
If enabled, this
limits the maximum number of starts permitted per
hour. This setpoint allows a maximum of 6 starts
per hour. Contact motor manufacturer.
If enabled, the soft
starter prevents another start attempt until the
programmed time has expired.
