68
Function:
Selects which information will be reported via analog output A.
Current as a percentage of motor full load current.
Motor temperature as a percentage of the motor service factor (calculated by the soft starter's
thermal model).
Motor kilowatts. 100% is motor FLC (Par. 1-1) multiplied by mains reference voltage (Par. 8-9).
Power factor is assumed to be 1.0.

1000
Motor kilovolt amperes. 100% is motor FLC (Par. 1-1) multiplied by mains reference voltage (Par.
8-9).
3 × V × I FLC
1000
Motor power factor, measured by the soft starter.
Function:
Selects the range of the output.
Function:
Calibrates the upper limit of the analog output to match the signal measured on an external current
measuring device.
Function:
Calibrates the lower limit of the analog output to match the signal measured on an external current
measuring device.
Function:
Selects whether the soft starter will auto-start after a specified delay, or at a time of day.
The soft starter will not auto-start.
The soft starter will auto-start after a delay from the next stop, as specified in Par. 5-2.
The soft starter will auto-start at the time programmed in Par. 5-2.
Function:
Sets the time for the soft starter to auto-start, in 24 hour clock format.
