Lenze 8600 series - V;F-Characteristic Control

The Io control, also referred to a “magnetizing-current control”
allows a considerabiy higher torque compared to the normal V/f-
characteristic control, without the motor being overexcited when
the drive is deloaded.
3.7.1 V/f-characteristic control
You have to Change from Io control (factory setiing) to V/f-
characteristic control if you want to supply several drives with
different loads or rated power from one controller. Also for pump and
blower drives to be operated with a Square characteristic, a V/f-
characteristic control is required.
V/f characteristic
With V/f-characteristic control the output voltage is controlled
according to the characteristic set via CO1 4 and CO1 6.
Via code CO14 you tan determine whether the characteristic
should have a linear or a Square shape.
