(2) Torque limit value selection and internal torque limit selection (TL1)
As shown below, the forward torque limit (parameter No. PA11), or reverse torque limit (parameter No.
PA12), the analog torque limit (TLA) and internal torque limit 2 (Parameter No. PC35) can be chosen using
the internal torque limit selection (TL1).
However, if the parameter No. PA11 and parameter No. PA12 value is less than the limit value selected by
TL/TL1, the parameter No. PA11 and parameter No. PA12 value is made valid.

(3) Limiting torque (TLC)
TLC turns on when the servo motor torque reaches the torque limited using the forward torque limit, reverse
torque limit or analog torque limit.
