VFC: Vmin boost
Boost of the V/f voltage characteristic in the range of small speeds or frequencies with V/f characteristic control
(VFCplus) and V/f control (VFCplus+encoder). This may increase the starting torque.
• After the motor to be used has been selected from the »Engineer« motor catalogue, the suitable value can be
entered automatically. An automatic detection via the motor parameter identification is possible as well.
• The general linear and quadratic V/f characteristics are shown in the illustrations below. The illustrations show
the impacts of the parameters used to adapt the characteristic shape.

Setting of motor overload (I²xt)
Operating threshold for the "OC6: Motor overload (I²xt)" error message
• If the calculated motor load reaches the operating threshold set here, the "Warning" error response is carried out
in the Lenze setting. The error response can be set in C00606.
