Torque Limit Configuration Method
Use one of these methods to set torque limits:
• Individually set the four torque limit quadrants using L7-01 to L7-04 [Torque Limit] .
• Use MFAI to individually set the four torque limit quadrants. 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 2.92 shows the configuration method for each quadrant.
Figure 2.92 Torque Limits and Analog Input Setting Parameters
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. The torque limit is 150% of the rated output current for HD and to 120% of the
rated output current for ND. 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 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 2.93 shows the relation between torque limits from parameters and torque limits from analog input.
