c. Torque limit signal (TL) and valid torque limit
Use the torque limit signal (TL) to select the torque limit made valid by internal torque limit
1 or analog torque limit (TLA) as indicated in Table 3-1:

d. Limiting torque (TLC)
TLC-SG are connected when the torque generated by the servo motor reaches the torque
set to internal torque limit 1 or analog torque limit.
2) In position (INP)
PF-SG are connected when the number of droop pulses in the deviation counter falls within
the preset in-position range (parameter No. 5). When the in-position range setting is large,
PF-SG may remain connected during low-speed operation.
