2.2 List of parameters
Description: Sets the open and closed-loop control mode of a drive.
Value: 0: U/f control with linear characteristic
1: U/f control with linear characteristic and FCC
2: U/f control with parabolic characteristic
3: U/f control with parameterizable characteristic
4: U/f control with linear characteristic and ECO
5: U/f control for drives requiring a precise freq. (e.g. textiles)
6: U/f control for drives requiring a precise frequency and FCC
7: U/f control for a parabolic characteristic and ECO
19: U/f control with independent voltage setpoint
20: Speed control (encoderless)
22: Torque control (encoderless)
Dependency: Only operation with U/f characteristic is possible if the rated motor speed is not entered (p0311).
Operation with a U/f characteristic is not supported for 1LE4 synchronous motors.
The output voltage is used for efficiency optimization for all U/f control types, load-dependent (see p0500 = 3).
Refer to: p0300, p0311, p0500, p1501
Notice: Active slip compensation is required in the U/f control types with Eco mode (p1300 = 4, 7). The scaling of the slip
compensation (p1335) should be set so that the slip is completely compensated (generally 100%).
The Eco mode is only effective in steady-state operation and when the ramp-function generator is not bypassed. In
the case of analog setpoints, if required the tolerance for ramp-up and ramp-down should be actively increased for
the ramp-function generator using p1148 in order to reliably signal a steady-state condition.
Note: Only by selecting closed-loop speed control (p1300 = 20) is it possible to change over in operation to closed-loop
torque control (p1501). At the changeover, the setting of p1300 does not change. In this case, the actual state is
displayed in r1407, bit 2 and bit 3.
For the open-loop control modes p1300 = 5 and 6 (textile sector), slip compensation p1335, resonance damping
p1338, and the Imax frequency controller are switched off internally so that the output frequency can be set precisely.
The Imax voltage controller remains active.
During operation (pulses enabled) the open-loop/closed-loop control mode cannot be changed by changing over
drive data sets.
Description: Sets the open and closed-loop control mode of a drive.
Value: 0: U/f control with linear characteristic
1: U/f control with linear characteristic and FCC
2: U/f control with parabolic characteristic
3: U/f control with parameterizable characteristic
4: U/f control with linear characteristic and ECO

20: Speed control (encoderless)
22: Torque control (encoderless)
Dependency: For Standard Drive Control (p0096 = 1), settings p1300 = 0, 2 are possible, for Dynamic Drive Control (p0096 = 2)
only p1300 = 20 can be set.
Only operation with U/f characteristic is possible if the rated motor speed is not entered (p0311).
