• High overload (HO):
HO is used if the application needs a high overload on the whole frequency range.Many loads can be consid-
ered to be high overloads.Typical high overloads are conveyors, compressors and positve displacement
pumps.
• Light overload (LO):
LO is used if the application has a parabolic frequency/torque characteristic like many fans and pumps.Light
overload offers the following possibilities with the same inverter:
- Higher rated inverter current r0207
- Higher rated inverter power r0206
- Higher threshold for I2t protection
If P0205 is modified in quick commissioning it immediately calculates various motor parameters:
1. P0305 Rated motor current
2. P0307 Rated motor power
3. P0640 Motor overload factor
It is recommended to modify P0205 first. Afterwards motor parameter may be adapted.
Motor parameter will be overridden by changing this sequence.
Values: 0: High overload
1: Light overload
Notice: Use setting 1 (light overload) only for light-overload applications (e.g. pumps and fans).
If used for high-overload applications, I2t warning will be produced too late, causing overheating in the motor.
Note: The parameter value is not reset by the factory setting (see P0970).
Description: Displays nominal rated motor power from inverter.
Dependency: Value is displayed in [kW] or [hp] depending on setting for P0100 (operation for Europe / North America).
