(5) Torque limit
CAUTION
Releasing the torque limit during servo lock may cause the servo motor to
suddenly rotate according to the position deviation from the instructed position.
(a) Torque limit and torque
By setting parameter No.28 (internal torque limit 1), torque is always limited to the maximum value
during operation. A relationship between the limit value and servo motor torque is shown below.

(b) Torque limit value selection
When internal torque limit selection (TL1) is made usable by parameter No.43 to 48, internal torque limit
2 (parameter No.76) can be selected. However, if the parameter No.28 value is less than the limit value
selected by parameter No.76, the parameter No.28 value is made valid.
