A

Set the speed limit as a percentage of the maximum frequency. (The max. frequency is 100%.) The

sign of the constant setting and the direction of the run command determine the direction in which

the speed is limited.

Setting +: Forward rotation; Speed is limited in the forward direction.

Reverse rotation; Speed is limited in the reverse direction.

Setting --: Forward rotation; Speed is limited in the reverse direction.

Reverse rotation; Speed is limited in the forward direction.

The speed limit value is zero for rotation opposite to the speed limit direction.

For example, when a positive value is set in d5-04 and the forward rotation command is ON, the

effective range of the torque control is from zero to the speed limit value in the forward direction

(when constant d5-05, the speed limit bias, is set to 0).
