If you use drives in applications where the vertical axis can fall, make sure that you know these items:
• 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 12.103 shows the relation between torque limits from parameters and torque limits from analog input.

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.

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.

When A1-02 = 0, 1, 5 [Control Method = V/f Control, PG V/f Control, PM OLVector], the drive rated current is
100%. When A1-02 = 2, 3, 4, 6, 7, 8 [OLVector, CLVector, Adv OLVector, PM AOLVector, PM CLVector, EZ
Vector], the motor rated current is 100%.
Note:
Use this function with L6-01 [Trq Det1 Select]. This parameter functions as an alternative to L6-02 [Trq Det1 Level].

V/f CL-V/f OLV
Enters the load torque limit if the motor rated torque is 100%.
V/f CL-V/f OLV
Enters the regenerative torque limit if the motor rated torque is 100%.
V/f CL-V/f OLV
Enters the torque limit that is the same for all quadrants for forward, reverse, and regenerative operation if the motor rated
torque is 100%.
V/f CL-V/f OLV
Enters a signal to adjust the overtorque/undertorque detection level.
