12.7 H: TERMINALS
614 SIEPCYEUOQ2V01A Q2V Technical Manual
• If you use this function to set the analog input value as the master frequency reference, set b1-01 = 1 [Freq. Ref.
Sel. 1 = Analog Input]. This setting value is the default value for terminals AI1 and AI2.
• The frequency reference is the sum of the input values for terminals AI1 and AI2 when they are used at the
same time. For example, when a 20% bias is input to terminal AI2 while a frequency reference of 50% is input
from terminal AI1, the calculated frequency reference will be 70% of the maximum output frequency.
■ 5: Freq Gain
Setting Value Function Description
5 Freq Gain
The drive multiplies the analog frequency reference with the input value from the MFAI set with this function.
Example: When you set frequency gain for terminal AI2
• H3-10 = 5 [AI2 Function Selection = Freq Gain]
• A 50% frequency gain is input to terminal AI2
• A frequency reference of 80% is input from terminal AI1
The calculated frequency reference is 40% of the maximum output frequency.
■ 6: OutVolt Bias
Setting Value Function Description
6 Output Voltage Bias
Set this parameter to input a bias signal to amplify the output voltage.
The gain (%) for the MFAI terminals AI1 and AI2 is 100% of the voltage class standard, which is 200 V for 200
V class drives and 400 V for 400 V class drives. The bias (%) for MFAI terminals AI1 and AI2 is 100% of the
voltage configured for E1-05 [Max Output Voltage].
Note:
The gain for each terminal AI1 and AI2 is set independently with H3-03 [AI1 Gain Setting] and H3-11 [AI2 Gain Setting]. The bias for
each terminal AI1 and AI2 is set independently with H3-04 [AI1 Bias Setting] and H3-12 [AI2 Bias Setting].

■ 7: TorqCompensation
Setting Value Function Description
7 TorqCompensation
Enters the torque compensation value if the motor rated torque is 100%.
■ 8: TorqRef/Lim
Setting Value Function Description
8 TorqRef/Lim
Enters the torque reference if the motor rated torque is 100%. This setting is the torque limit for speed control.
Note:
When you use L7-01 to L7-04 and analog inputs to set torque limits for the same quadrant, it will enable the lower torque limit.
■ 9: FW Trq Lim
Setting Value Function Description
9 FW Trq Lim
Enters the forward torque limit if the motor rated torque is 100%.
WARNING! Sudden Movement Hazard. Set correct torque limits for applications, for example elevator applications. If you set
torque limits incorrectly, motor torque that is not sufficient can cause damage to equipment and cause serious injury or death.
