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 terminal A1 is 80% and a gain of 50% is applied from
analog input terminal A2, the resulting frequency reference will be 40% of the maximum output frequency.
Setting 2: Auxiliary Reference 1
Sets the auxiliary frequency reference 1 when multi-step speed operation is selected. Refer to Multi-Step Speed
Selection on page 165 for details.
Setting 3: Auxiliary Reference 2
Sets the auxiliary frequency reference 2 when multi-step speed operation is selected. Refer to Multi-Step Speed
Selection on page 165 for details.
Setting 4: Output 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 5: Accel/Decel Time Gain
Adjusts the gain level for the acceleration and deceleration times set to parameters C1-01 through C1-04.
The acceleration time used by the drive is calculated by multiplying the this gain level to C1- as follows:
C1- × Accel/decel time gain = Drive accel/decel time

Setting 6: DC Injection Braking Current
The current level used for DC Injection Braking. Set as a percentage of the maximum output current using.

Setting 7: Torque Detection Level
Using this setting, the overtorque/undertorque detection level for torque detection 1 (L6-01) can be set by an analog
input. The analog input will replace the level set to L6-02. An analog input of 100% (10 V or 20 mA) will set a torque
detection level equal to 100% drive rated current / motor rated torque. Adjust the analog input gain if higher detection
level settings are required. Refer to L6: Torque Detection on page 231 for details on torque detection.
