Function:
[0.0 - Enter the voltage at each frequency
point to manually form a U/f character-
istic matching the motor.
The frequency points are defined in
par. 1-56 U/f Characteristic - F.
This parameter is an array parameter
[0-5] and is only accessible when
par. 1-01 Motor Control Principle is set to
U/f [0].
Function:
[Applica- Enter the frequency points to manual-
ly form a U/f-characteristic matching
the motor.
The voltage at each point is defined in
par. 1-55 U/f Characteristic - U.
This parameter is an array parameter
[0-5] and is only accessible when
par. 1-01 Motor Control Principle is set
to U/f [0].
Function:
Control the percentage of the magnetizing
current for the pulses used to detect the motor
direction. Reducing this value will reduce the
generated torque. 100% means nominal motor
current. The parameter is active when
par. 1-73 Flying Start is enabled. This parameter
plus
is only available in VVC .

Function:
[0 - 500 Control the percentage of the frequency for the
pulses used to detect the motor direction.
Increasing this value will reduce the generated
torque. 100% means 2 times the slip frequency.
The parameter is active when par. 1-73 Flying
Start is enabled. This parameter is only available
plus
in VVC .
Function:
[0 - 300 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.
