Scalar Control (V/f)
P0589 – Level of Minimum Applied Voltage
Adjustable
Range:
40 to 80 %
Factory
Setting:
40 %
Properties:
cfg, V/f
Access groups
via HMI:
Description:
This parameter defines the minimum voltage value that will be applied to the motor when the energy saving function
is active. This minimum value is relative to the voltage imposed by the V/f curve for a certain speed.
P0590 – Min. Speed Energy Saving
Adjustable
Range:
0 to 1800 rpm
Factory
Setting:
600 (525) rpm
Properties:
cfg, V/f
Access groups
via HMI:
Description:
This parameter defines the minimum speed value at which the energy saving function will remain active. The
hysteresis for the minimum speed level is of 2 Hz.
P0591 – Hysteresis for the Maximum Torque Level
Adjustable
Range:
0 to 30 %
Factory
Setting:
10 %
Properties:
cfg, V/f
Access groups
via HMI:
Description:
Hysteresis used to activate and deactivate the energy saving function. If the function is active and the output current
oscillates, it is necessary to increase the value of the hysteresis.
