F: Not Used
Setting Value Function
F Not Used
When you set a terminal that is not in use to F, you can use the signal input to the terminal as PLC analog signal input
through MEMOBUS/Modbus communications or the communication option. This input signal does not have an effect
on drive operation. This functions the same as setting 1F (Through Mode).

10: Forward Torque Limit
Setting Value Function
10 Forward Torque Limit
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.
Torque Limit Configuration Method
Use one of these methods to set torque limits:
• Use L7-01 to L7-04 [Torque Limit] to set the four torque limit quadrants individually.
• Use MFAI to set the four torque limit quadrants individually. Set H3-02, H3-10 = 10, 11, 12 [MFAI Function Select
= Forward/Reverse/Regenerative Torque Limit].
• Use MFAI to set all four torque limit quadrants together. Set H3-02, H3-10 = 15 [General Torque Limit].
• Use a communication option to set all four torque limit quadrants together.
Figure 2.76 shows the configuration method for each quadrant.
Note:
• When L7-01 to L7-04 and analog inputs or communication option torque limits set torque limits for the same quadrant, the lower value is
enabled.
In this example of parameter settings, the torque limit for quadrant 1 is 130% and the torque limit for quadrants 2, 3, and 4 is 150%.
Settings: L7-01 = 130%, L7-02 to L7-04 = 200%, and MFAI torque limit = 150%
• The drive output current limits maximum output torque to 120% of the rated output current. The actual output torque is not more than the
limits of the drive rated output current when you set the torque limit to a high value.
If you use drives in applications where the vertical axis can fall, make sure that you obey these precautions:
• Correctly configure drives and motors.
• Correctly set parameters.
• You can change parameter values after you do Auto-Tuning.
• Use a system that will not let the vertical axis fall if the drive fails.
Figure 2.77 shows the relation between torque limits from parameters and torque limits from analog input.

V/f OLV/PM EZOLV OLV/PM
Use this setting for unused terminals or to use terminals in through mode.
V/f OLV/PM EZOLV OLV/PM
Enters the forward torque limit when the motor rated torque is 100%.
