- 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 V/f characteristics and is calculated as follows:
Voltage boost = p0305 (rated motor current x p0350 (stator/primary section resistance) x p1310 (permanent voltage
boost)
Dependency:
Setting in p0640 (motor overload factor [%]) limits the boost.
For vector control, the permanent voltage boost (p1310) has no effect as the drive converter automatically sets the
optimum operating conditions.
Refer to: p1300, p1311, r1315
Notice:
The voltage boost increases the motor temperature (particularly at zero speed).
Note:
The voltage boost is only effective for V/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)).
However, these parameters are assigned the following priorities: p1310 > p1311
Description:
p1311 only results in a voltage boost when accelerating and generates a supplementary torque/force 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 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 %
Dependency:
Setting in p0640 (motor overload factor [%]) limits the boost.
Refer to: p1300, p1310, r1315
Notice:
The voltage boost results in a higher motor temperature increase.
Note:
The voltage boost when accelerating can improve the response to small, positive setpoint changes.
Assigning priorities for the voltage boosts: refer to p1310
Description:
Displays the total resulting voltage boost in volt (p1310 + p1311).
