8.8 Parameter descriptions
8.8.1 Notes on optional parameters
The following sections provide a description for all the parameters, whether available by default or optional. Optional parameters are
only available if the relevant option card is fitted to the soft starter. For a detailed list of optional parameters, refer to the table below.
Table 8-5 Optional parameters
Inputs C and D are only available if the input/output expansion card
is installed.
Outputs D, E and F are only available if the input/output expansion
card is installed.
Ground fault protection is only available if the RTD/PT100 and
ground fault protection card is fitted.
The analog input is only available if the input/output expansion card
is installed.
Analog Output B is only available if the input/output expansion card
is installed.
Analog B Maximum Adjustment
Analog B Minimum Adjustment
PT100 inputs B to G are only available if the RTD/PT100 and
ground fault protection card has been installed.
Ground Fault and PT100 inputs B to G are only available if the
RTD/PT100 and ground fault protection card has been installed.
8.8.2 Group 1 - Primary motor set
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
suitable for most applications. Consult the motor datasheet before changing these settings.
Matches the starter to the connected motor's full load current. Set to the full load current (FLC) rating shown on the motor
nameplate.
Sets the locked rotor current of the connected motor, as a percentage of full load current. Set according to the motor datasheet.
