5.7 H: Terminal Functions
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 147 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 V/f Control, this function is based
Refer to L6: Torque Detection on page 205
on 100% of the drive rated current. for details on torque detection.
Setting B: PID Feedback
An input set for this function supplies the PID feedback value. This setting requires PID operation to be enabled in b5-01.
Refer to PID Feedback Input Methods on page 131.
Setting C: PID Setpoint
An input set for this function supplies the PID setpoint value. The frequency reference selected in parameter b1-01 no longer
becomes the PID se point. This setting requires PID operation to be enabled in b5-01. Refer to PID Setpoint Input
Methods on page 131.
Setting E: Motor Temperature
In addition to or in place of the oL1 (motor overload) fault detection, it is possible to use a PTC (Positive Temperature
Coefficient) thermistor for motor insulation protection. Refer to Motor Protection Using a Positive Temperature Coefficient
(PTC) on page 191 for detailed explanations.
Setting F: Not Used
Any analog input that is not used should be set to F. When set to "F", an input does not affect any drive function but the input
level can be read out by a PLC via a communication option or MEMOBUS/Modbus communications (through mode). This
way drive analog inputs can be used to read out external sensor values if there is a lack of PLC analog inputs.
Setting 16: Differential PID Feedback
If an analog value is set for this function, the PID controller is set for differential feedback. The subtraction of the PID feedback

input value and the differential feedback input value builds the feedback value that is used to calculate the PID input.
to PID Feedback Input Methods on page 131.

Setting 1F: Not Used
An input does not affect any drive function, but the input level can still be read out by a PLC via a communication option or
MEMOBUS/Modbus communications.
Setting 20: HAND Frequency Reference
Provides the HAND frequency reference when HAND Mode Frequency Reference Source parameter P5-01 is set to 1.
Setting 41: Output Voltage Gain
Allows the user to change the output voltage by adjusting the voltage reference via one of the analog input terminals or with
MEMOBUS/Modbus.
