for the torque and current limitation (C03 and C05).

Related torque: The parameter B18 shows the reference value for percentage of torque values
(such as C03, C05, E62 and E66) in every control mode (B20).

Control mode: Specifies the type of motor control.
NOTE
- With control type "0: V/f-control," there is no current or torque limitation. Similarly, connection to a
rotating motor is not possible ("capturing").
- Control type 64:Servo-control is not available with the FDS 5000 inverter.
0: V/f-control; Simplest type of control for the asynchronous machine (ASM). The corresponding
reference value frequency and voltage are calculated from the specified speed and rigidly
applied to the motor.
1: Sensorless vector control;
2: Vector control;
64: Servo-control
; Type of control for servo drives.

V/f-characteristic: Switch between linear and square characteristic curve.
0: Linear; Voltage/frequency characteristic curve is linear. Suitable for all applications.
1: Square; Square characteristic curve for use with fans and pumps. The characteristic curve is
continued linearly starting at the nominal frequency (B15).

V/f-factor: Offset factor for the increase of the V/f characteristic curve. The increase with V/F
factor = 100% is specified by V-nominal (B14) and f-nominal (B15).

V/f-Boost: The term boost means an increase in voltage in the lower speed range whereby a
higher startup torque is available. With a boost of 100% the nominal motor current flows at 0 Hz. To
specify the required boost voltage, the stator resistance of the motor must be known.
For this reason, with motors without electronic nameplate, it is essential that B41 (autotune motor)
be performed!!
With STÖBER standard motors, the stator resistance of the motor is specified by the choice of
motor.
