Setting 0: Frequency Bias
The input value of an analog input set to this function will be added to the analog frequency
reference value. Use this setting also when only one analog input is used to supply the
frequency reference.
By default both analog inputs A1 and A2 are set for this function. Using both A1 and A2 at
the same time increases the frequency reference by the total of both inputs.
Example: If the analog frequency reference by analog input A1 is 50% and a bias of 20% is
applied by analog input A2, the resulting frequency reference will be 70% of the maximum
output frequency.
Setting 1: Frequency Gain
The input value of an analog input set to this function will be multiplied with the analog
frequency reference value.
Example: If the analog frequency reference from analog input A1 is 80% and a gain of 50%
is applied from analog input A2, the resulting frequency reference will be 40% of the
maximum output frequency.
Setting 2: Auxiliary Reference
Sets the auxiliary frequency reference when Multi-Step Speed operation is selected. Refer to
Multi-Step Speed Selection on page 95 for details.
Setting 4: Voltage Bias
Voltage bias boosts the output voltage of the V/f curve as a percentage of the maximum
output voltage (E1-05). Available only when using V/f Control.
Setting 7: Overtorque/Undertorque Level
Overtorque level sets the overtorque/undertorque detection level using the analog input. This
works with Torque Detection Selection 1 (L6-01) and will take the place of the torque
detection level set to L6-02. For general Open Loop Vector Control, this function is based on
100% of the motor rated torque. For V/f Control and PM Open Loop Vector, this function is
based on 100% of the drive rated current. Refer to
L6: Torque Detection on page 211 for
details on torque detection.
