(c) 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.
1) 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.

A relationship between the applied voltage of the analog torque limit (TLA) and the torque limit value
of the servo motor is shown below. Torque limit values will vary about 5 relative to the voltage
depending on products.
At the voltage of less than 0.05V, torque may vary as it may not be limited sufficiently. Therefore, use
this function at the voltage of 0.05V or more.

2) Torque limit value selection
Use parameters No.43 through 48 to enable external torque limit (TL) and internal torque limit (TL1).
Torque limit values can be selected as shown in the following table. However, if the parameter No.28
value is less than the limit value selected by TL/TL1, the parameter No.28 value is made valid.
