• To set individually for each quadrant, use Pr.812 Torque limit level (regeneration), Pr.813 Torque limit level (3rd
quadrant), Pr.814 Torque limit level (4th quadrant). When "9999" is set, Pr.22 setting is regarded as torque limit level
in all the quadrants.

 Torque limit level using analog input (terminal 4) (Pr.810 = "1", Pr.858)
• The torque is limited with the analog input of terminal 4. (External torque limit)
• Torque limit using analog input is valid with a limit value lower than the internal torque limit (Pr.22, Pr.812 to Pr.814). (If
the torque limit using analog input exceeds the internal torque limit, the internal torque limit is valid.)
• For inputting from terminal 4, set Pr.858 Terminal 4 function assignment = "4".
• Torque limit using analog input can be calibrated by the calibration parameters C38 to C41. (Refer to

 Internal torque limit 2 (Pr.810 = "2", Pr.805, Pr.806)
• The setting value of Pr.805 or Pr.806 is used as the torque limit value.
• When the CC-Link, CC-Link IE TSN, or CC-Link IE Field Network is used, the torque limit value can be input using a remote
register (RWwC).

*1 The torque limit setting is defined as an absolute value.
*2 The torque limit value can also be set using the operation panel.
*3 The torque can also be limited by setting a value in Pr.805 or Pr.806.
*4 The setting range if set by the operation panel is "673 to 1327 (-327% to 327%)"; and the setting increment is 1%.
