Siemens G130 List Manual page 373

Note: For 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).
For 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).
For bit 02:
Only for internal Siemens use.
For 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 %
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:
- magnetize the induction motor.
- hold the load.
- compensate for losses in the system.
This is the reason that the output voltage can be increased using p1310.
The voltage boost can be used for both linear as well as square-law U/f characteristics.
Dependency: The starting current (voltage boost) is limited by the current limit p0640.
The accuracy of the starting current depends on the setting of the stator and feeder cable resistance (p0350, p0352).
Refer to: p1300, p1311, p1312, r1315
Notice: The starting current (voltage boost) increases the motor temperature (particularly at zero speed).
Note: The starting current as a result of the voltage boost is only effective for U/f control (p1300).
The boost values are combined with one another if the permanent voltage boost (p1310) is used in conjunction with
other boost parameters (acceleration boost (p1311), voltage boost for starting (p1312)).
However, these parameters are assigned the following priorities: p1310 > p1311, p1312

Description: p1311 only results in a voltage boost when accelerating and generates a supplementary torque to accelerate the
load.
The voltage boost becomes effective for a positive setpoint increase and disappears as soon as the setpoint has
been reached. The build-up and withdrawal of the voltage boost are smoothed.
The magnitude of the boost in Volt at a frequency of zero is defined as follows:
Voltage boost [V] = 1.732 * p0305 (rated motor current [A]) x r0395 (stator/primary section resistance [ohm]) x p1311
(voltage boost when accelerating [%]) / 100 %
