The inverter and motor requirements are determined by the speed range and torque requirements of the load. The relationship between speed and torque for different loads (constant torque loads or variable torque loads).

Possible Settings:

0Constant torque

1Variable torque

Note:

Constant torque (CT):

CT is used if the application needs a constant torque on the whole frequency range. Many loads can be considered to be constant torque loads. Typical constant torque loads are conveyors, compressors and positve displacement pumps (see diagram).

Variable torque (VT):

VT is used if the application has a parabolic frequency-torque characteristic like many fans and pumps.

Variable torque allows 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:

-P0305 Rated motor current

-P0307 Rated motor power

-P0640 Motor overload factor
