8.4. Parameter Descriptions
• 1 Motor Details
NOTE
Parameter 1B determines the trip current for motor overload protection. The default setting of
parameter 1B provides Motor Overload Protection: Class 10, Trip Current 105% of FLA (full load
amperage) or equivalent.
1A – Motor FLC
Range: Model dependent
Description: Matches the starter to the connected motor's full load current. Set to the full load
current (FLC) rating shown on the motor nameplate.
1B – Locked Rotor Time
Range: 0:01 - 2:00 (minutes:seconds) Default: 10 seconds
Description: Sets the maximum length of time the motor can sustain locked rotor current from cold
before reaching its maximum temperature. Set according to the motor datasheet.
1C – Motor FLC-2
Range: Model dependent
Description: Sets the secondary motor's full load current.
1D – Locked Rotor Time-2
Range: 0:01 - 2:00 (minutes:seconds) Default: 10 seconds
Description: Sets the maximum length of time the motor can sustain locked rotor current from cold
before reaching its maximum temperature. Set according to the motor datasheet.
1E – Dual Thermal Model
Options: Single (default)
Dual
Description: Activates dual thermal modelling. The dual thermal model is required only if the
LV-DS is controlling two physically separate motors.
NOTE
The second thermal model is only active if parameter 1E Dual Thermal Model is set to 'Dual' and the
starter is using the secondary motor set (a programmable input is set to 'Motor Set Select' and the
input is active).
• 2 Primary Start/Stop
2A – Start Mode
Options: Constant Current (default)
Adaptive Control
Description: Selects the soft start mode.
2B – Current Limit
Range: 100% - 600% FLC Default: 350%
Description: Sets the current limit for constant current and current ramp soft starting, as a
percentage of motor full load current.
2C – Initial Current
Range: 100% - 600% FLC Default: 350%
Description: Sets the initial start current level for current ramp starting, as a percentage of motor
full load current. Set so that the motor begins to accelerate immediately after a start
is initiated.
If current ramp starting is not required, set the initial current equal to the current limit.
2D – Start Ramp Time
Range: 1 - 180 (seconds) Default: 10 seconds
Description: Sets the total start time for an Adaptive Control start or the ramp time for current ramp
starting (from the initial current to the current limit).
2E – Kickstart Level
Range: 100% - 700% FLC Default: 500%
Description: Sets the level of the kickstart current.
