V/f characterisc shape
(V/f charac.shape)
•
Seng can only be changed if the inverter is inhibi-
ted.
Selecon of the V/f characterisc shape for the adaptaon to dierent
load proles.
0 Linear Linear characterisc for drives with constant load torque over the speed.
4Linear V/f characterisc ^ 167
1 Quadrac Square-law characterisc for drives with a linear or square-law load tor-
que over the speed.
•
Square-law V/f characteriscs are preferably used for centrifugal
pumps and fan drives.
•
Please always check whether the corresponding drive is suitable for
operaon with a square-law V/f characterisc!
•
If your pump drive or fan drive is not suitable for operaon with a
square-law V/f characterisc, use the linear V/f characterisc instead.
4Square-law V/f characterisc ^ 168
2 Mulpoint (from version 03.00) Linear characteriscs with an addional centre characterisc point for
the purpose of adaptaon to specic load proles.
4User-denable V/f characterisc ^ 169
3 Eco (from version 02.00) Linear characterisc with energy opmisaon in the paral load opera-
onal range.

0 ... [230]* ... 5000 V
* Default seng depending on the size.
Base voltage and base frequency dene the V/f rao and thus the gradi-
ent of the V/f characterisc.
•
The V/f base voltage is usually set to the rated motor voltage
0x2C01:007 (P320.07).
•
The V/f base frequency is usually set to the rated motor frequency
0x2C01:005 (P320.05).

Motor control mode
(Motor ctrl mode)
•
Seng can only be changed if the inverter is inhibi-
ted.
Selecon of the motor control type.
2 Servo control (SC ASM) (from version 02.00) This control mode is used for servo control of an asynchronous motor.
4Servo control for asynchronous motors (SC-ASM) ^ 176
3 Sensorless control (SL PSM) (from
version 02.00)
This control type is used for the sensorless control of a synchronous
motor.
•
Control mode is possible up to a rated power of maximally 22 kW.
4Sensorless control for synchronous motors (SL-PSM) ^ 178
4 Sensorless vector control (SLVC) This control type is used for sensorless vector control of an asynchro-
nous motor.
4Sensorless vector control (SLVC) ^ 173
6 V/f characterisc control (VFC open loop) This control mode is used for the speed control of an asynchronous
motor via a V/f characterisc and is the simplest control mode.
4V/f characterisc control (VFC) ^ 166
7 V/f characterisc control (VFC closed loop)
(from version 04.00)
The control mode is used for speed control of an asynchronous motor
via a V/f characterisc with speed feedback.
A motor encoder must be connected to the inverter and set as feedback
system for the motor control.

•
The inverter provides dierent funcons by means of which the drive behaviour can be
further opmised.4Opmisaon of motor control ^ 182
•
An opmisaon of the control loops is not mandatory for this motor control type but may
lead to a
beer control mode. 4Opmisaon of the control loops ^ 193
