Group 1 - Primary Motor Settings
The motor data parameters are critical to the correct operation of the soft starter's thermal model, and to the motor
overload protection. Always set Pr 1A to suit the motor's characteristics. The default settings of Pr 1B , 1C and 1D are
WARNING
suitable for most applications. Consult the motor datasheet before changing these settings.
No
Function
1A
Motor Full Load Current
Matches the starter to the connected motor's full load current. Set to the full load current (FLC) rating shown on the motor
nameplate.
When connecting in inside delta, enter the motor full load current (FLC) for Pr 1A . The Digistart D3 will automatically detect whether
the motor is connected in-line or inside delta and will calculate the correct inside delta current level.
No
Function
1B
Locked Rotor Current
Sets the locked rotor current of the connected motor, as a percentage of full load current. Set according to the motor datasheet.
