SP8.3 Area Under Curve Protection: If enabled, this 

secondary start protection uses both the basic start 

protection and the area under the curve protection.

 

•  Max I*I*T Start: 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. 

SP8.4 Current Over Curve: Learns the motor’s starting 

characteristics and protects the motor based upon 

the learned curve. It is useful when commissioning a 

new motor.

•  Learn: 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.

•  Learned Start Curve Basis: The maximum allowed 

deviation above or below the start curve before a trip 

is generated.

•  Time for Sampling: The time the soft starter 

continues to sample the start curve characteristic 

during learn the mode.

Configures 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 Basic Run Overload Curve

 Time: 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. 

 

•  Run Locked Rotor Current:

 

  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. 

•  Coast Down Timer: If enabled,

 

  this prevents the motor from

 

  restarting for the programmed

 

  amount of time, after a stop

 

  command is given.

•  Start Curve Locked Rotor Time: The locked 

rotor time can be set to the OL Class default 

chosen in Setpoint Page 1 or  to a specific 

time. The overload condition must exist for the 

programmed amount of time before a trip occurs.

•  Start Locked Rotor Current: 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. 

•  Acceleration Time Limit: If the motor does not 

enter run mode (reach at speed) within the preset 

time, the unit trips on acceleration time limit.  

•  Number of Starts per hour: 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. 

•  Time Between Starts: If enabled, the soft 

starter prevents another start attempt until the 

programmed time has expired.
