(5) Torque limit
(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.
