Voltage induced by the motor (rotor voltage / 1000 rpm).
For permanently excited synchronous motors, the e.m.f. constant
describes the r.m.s. value of the line-to-line voltage (phase voltage)
induced in idle state by the motor (reference: 1000 rpm, 20 °C).

Seng can only be changed if the inverter is inhibi-

The rated motor current that needs to be set here serves as a reference
value for dierent parameters that involve a seng for/display of a cur-
rent value in percent.
Example:
•
Motor rated current = 1.7 A
•
Max current 0x6073 (P324.00) = 200 % Motor rated current = 3.4 A

The rated motor torque to be set here serves as a reference value for
dierent parameters with a seng/display of a torque value in percent.
Example:
•
Motor rated torque = 1.65 Nm
•
Max torque 0x6072 (P326.00) = 250 % Motor rated torque = 4.125 Nm

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 motor (SC-ASM)^ 169
A motor encoder must be connected to the inverter. This motor encoder
is used as a feedback system for the motor control.
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 22 kW.
4Sensorless control for synchronous motor (SL-PSM)^ 170
4 Sensorless vector control (SLVC) This control type is used for sensorless vector control of an asynchro-
nous motor.
4Sensorless vector control (SLVC) ^ 174
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.

^ 176
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. This motor encoder
is used as a feedback system for the motor control.
