Description: Sets the open and closed loop control mode of a drive.
Values: 0: V/f control with linear characteristic
1: V/f control with linear characteristic and FCC
2: V/f control with parabolic characteristic
3: V/f control with parameterizable characteristic
5: V/f control for drives requiring a precise freq. (e.g. textiles)
6: V/f control for drives requiring a precise frequency with FCC
18: I/f control with fixed current
19: V/f control with independent voltage setpoint
20: Speed control (sensorless)
21: Speed control (with encoder)
22: Torque control (sensorless)
23: Torque control (with encoder)
Dependency: Closed-loop speed or torque control (with encoder) cannot be selected if the encoder type is not entered (p0400).
Closed-loop speed or torque control can be selected if the closed-loop speed/torque control was selected as oper-
ating mode (p0108 bit 2).
Only operation with V/f characteristic is possible if the rated motor speed is not entered (p0311).
A reluctance motor can only be operated in a V/f control mode (p1300 < 20).
Refer to: p0108, r0108, p0300, p0311, p0400, p1501
Note: The closed-loop torque control can only be changed over in operation (p1300 = 20, 21) by selecting the closed-loop
speed control (p1501). At the changeover, the setting of p1300 does not change. In this case, the actual state is dis-
played in r1407, bit 2 and bit 3.
For the open-loop control modes p1300 = 5 and 6 (textile sector), the slip compensation p1335 and the resonance
damping p1338 are internally switched-out (disabled) in order to be able to precisely set the output frequency.
Separately-excited synchronous motors can only be operated in the modes p1300 = 21 and 23 - or for diagnostic
purposes in the modes p1300 = 0, 3 and 18. For I/f control (p1300 = 18), the current amplitude can be set using
p1609. Both for V/f as well as for I/f control only a small load may be applied to the separately-excited synchronous
motor because the excitation current is not calculated as a function of the load.
During operation (the pulses enabled) the open-loop/closed-loop control mode cannot be changed by changing-
over drive data sets.
p1300 is pre-assigned depending on r0108.2 and p0187.
Description: Defines the voltage boost as a [%] referred to the rated motor current (p0305).
The magnitude of the permanent voltage boost is reduced with increasing frequency so that at the rated motor fre-
quency, the rated motor voltage is present.
The magnitude of the boost in Volt at a frequency of zero is defined as follows:
Voltage boost [V] = p0305 (rated motor current [A]) x p0350 (stator/primary section resistance [ohm]) x p1310 (per-
manent voltage boost [%]) / 100 %
At low output frequencies, there is only a low output voltage in order to maintain the motor flux. However, the output
voltage can be too low in order to achieve the following:
