4.4.3 Basic motor sengs
Check the following default sengs for the motor and motor control and adapt them, if
required.
Drive behaviour b
y default
By default, the V/f characterisc control with a linear characterisc is preset as motor control
for asynchronous motors. The V/f characterisc control is a motor control for convenonal
frequency inverter applicaons. It is based on a simple and robust control mode for the opera-
on of asynchronous motors with a linear or square-law load torque characterisc (e.g. fan).
Because of the minimal parameterisaon eort, such applicaons can be commissioned easily
and quickly.
The default sengs of the parameters ensure that the inverter is ready for operaon imme-
diately and the motor works adequately without further parameterisaon if an inverter and
a 50 Hz asynchronous machine with matching performances are assigned to each other.

Selecon of the motor control type.
4 Sensorless vector control (SLVC) This control type is used for sensorless vector control of an asynchro-
nous motor.

6 V/f characterisc control (VFC open loop) This control mode is used for the speed control of an asynchronous
motor via a V/f characterisc and is the simplest con
trol mode.

The rated motor current to be set here serves as a reference value for
dierent parameters with a seng/display in percent.
Relevant parameters:
