5.7 Servo control (SC)
Field-oriented servo control (SC) is based on a decoupled, separate control of the torque-
producing and the field-producing current component. The operating mode is based on a
field-oriented, cascaded controller structure with feedback function and enables dynamic
and stable operation in all of the four quadrants.
Generally, the servo control offers the same advantages as the sensorless vector control
(SLVC), i.e. compared to the V/f characteristic control, the servo control (SC) can be used to
achieve
A higher maximum torque throughout the entire speed range
A higher speed accuracy
A higher concentricity factor
A higher level of efficiency
The implementation of torque-actuated operation with speed limitation
The limitation of the maximum torque in motor and generator mode for speed-
actuated operation

• We recommend to select a power-adapted combination of inverter and
motor.
• The Lenze setting permits the operation of a power-adapted motor. Optimal
operation is only possible if either
:
– the motor is selected via the Lenze motor catalogue
– the motor nameplate data are entered and motor parameter identification
is carried out afterwards
- or -
– the nameplate data and equivalent circuit data of the motor (motor
leakage inductance and mutual motor inductance, slip compensation and
motor stator resistance) are entered manually.
• When you enter the motor nameplate data, take into account the phase
connection implemented for the motor (star or delta connection). Only enter
the data applying to the selected connection type.
• Speed feedback parameterisation is required.
