Load Depend. Setting - Danfoss VLT FC 102 Programming Manual

Programming Guide | VLT® HVAC Drive FC 102
Data type: Uint16
The parameter is active when parameter 1-73 Flying Start is enabled. The value range and function depend on parameter 1-10 Motor
Construction: [0] Asynchron: [0-500%] Control the percentage of the frequency for the pulses used to detect the motor direction.
Increasing this value reduces the generated torque. In this mode, 100% means 2 times the slip frequency. [1] PM non salient and [2]
PM, salient IPM: [0-10%] This parameter defines the motor speed (in % of nominal motor speed) below which the parking function (see
parameter 2-06 Parking Current and parameter 2-07 Parking Time) becomes active. This parameter is only active when parameter 1-70
Start Mode is set to [1] Parking and only after starting the motor.

1-60 Low Speed Load Compensation
Default value:
100%
Setup: All setups
Data type:
Int16
Parameter 1-60 Low Speed Load Compensation only has effect when parameter 1-10 Motor Construction = [0] Asynchron.
Enter the % value to compensate voltage in relation to load when the motor is running at low speed and obtain the optimum U/f
characteristic. The motor size determines the frequency range within which this parameter is active.
