[4-5] Speed limit value conditioning (schematic diagram)
The speed limit value is defined in the Lenze setting via the analog input 2.
r The defined speed limit value refers to the direction of rotation which can be set freely
with positive torque.
r The speed limit value in negative direction of rotation equals, according to amount, the
limit value for the positive direction of rotation.
r If the speed of the drive is inside the limitations, the motor generates the specified
torque.
r If the positive or negative speed limit value (for CW or CCW rotation) is reached, the
drive changes to the speed-controlled operation. The set speed limit values are not
exceeded.
r If the specified speed limit value directly corresponds to the line speed, the internal
limit value can be increased by entering an offset in C03008.
