5.7 H: Terminal Functions
n Multi-Function Analog Input Terminal Settings
This section describes the various functions that can be assigned to terminals A1 and A2 by setting H3-02 and H3-10.
Note: The scaling of all input functions depends on the gain and bias settings for the analog inputs. Set these to appropriate values when selecting
and adjusting analog input functions.

2 Auxiliary Frequency Reference
4 Output Voltage Bias
7 Overtorque/Undertorque Detection Level

E Motor Temperature (PTC input)
F Not used/Through Mode
<1> Available in drive software versions PRG: 1016 and later.
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.
page 160 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.
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
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.
Methods on page 137.
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.
