1 To specify the torque limit value by an analog input, refer to Pr5.21 “Analog torque limit
function”.
• Setup of rate of change after torque limit switchover
When applying Pr5.21 “Torque limit selection” = 3, changing rate of torque (slope) after
selecting new torque limit can be changed.
When changing from the 1st torque limit to 2nd torque limit, the changing rate (slope) set at
Pr5.23 “Torque limit selection setup 1” is applied; after changing from the 2nd torque limit
to 1st torque limit, the changing rate (slope) set at Pr5.24 “Torque limit selection setup 2” is
applied. The sign of the changing rate is automatically selected by the driver according to the
difference in value between the 1st and 2nd torque limit.
If Pr5.23 “Torque limit selection setup 1” and Pr5.24 “Torque limit selection setup 2” are set to 0,
switchover is instantaneous.

When the 1st torque limit (Pr0.13) and 2nd torque limit (Pr5.22) are changed from the front
panel or through communication, the changing rate setup is ignored and the new torque limit
value is immediately and directly applied. That is, changing rate setting is effective only when
the selection is made by using the torque limit select input (TL-SEL).
