2.2 List of parameters
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
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.
For the open-loop control modes p1300 = 4 and 7 (Eco mode), the efficiency can be optimized by varying the voltage
(when the operating point is constant).
Separately-excited synchronous motors can only be operated in modes p1300 = 20, 21 and 23 - or for diagnostic
purposes in modes p1300 = 0, 3 and 18. For I/f control (p1300 = 18), the current amplitude can be set using p1609.
Both for U/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 (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: Sets the configuration for the U/f control.
Note: Re bit 00:
If the bit is set the device will always start up with setpoint angle zero on pulse enable. This also affects the setpoint
angle for DC braking (p1231).
Re bit 01:
If the bit is set, in the case of U/f control with independent voltage setpoint (p1300 = 19) and negative setpoint
voltages at the input of p1330, the setpoint angle is rotated through 180 degrees, thereby achieving a negative output
voltage. The voltage boost is in this case not active (p1310, p1311).
Re bit 02:
Only for internal Siemens use.
Re bit 06:
Only for p1300 = 19.
When the bit is set, the setpoints from p1330 for pulse inhibit are transferred without any delay.
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
frequency, 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] = 1.732 x p0305 (rated motor current [A]) x r0395 (stator/primary section resistance [ohm]) x p1310
(permanent voltage boost [%]) / 100 %
