(5) Torque limit
(a) Torque limit and torque
By setting parameter No. 28 (internal torque l imit 1), torque is alw ays 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 (TL 1) is made usable by parame ter No. 43 to 48, in ternal
torque limit 2 (parameter No. 76) can be selected. However, if the parame ter No. 28 valu e is less
than the limit value selected by parameter N o.76, the parameter No. 28 value is made v alid.
