Parameter Description

Dependency:

Continous boost P1310 has no effect during vector operation because the inverter calculates continously the optimum operating conditions.

Note:

-Increasing the boost levels increases motor heating (especially at standstill).

-The boost values are combined when continuous boost (P1310) used in conjunction with other boost parameters (acceleration boost P1311 and starting boost P1312).

-However priorities are allocated to these parameters as follows: P1310 > P1311 > P1312

-The total boost is limited by following equation:

VBoost 3 Rs IMot = 3 P0305P0350

-Setting in P0640 (motor overload factor [%]) limits the boost:

VBoost P0640

P1311 will only produce boost during ramping, and is therefore useful for additional torque during acceleration and deceleration. Contrary to P1312, that is only active when an ON command is given, p1311 is active after each acceleration resp. deceleration. The boost is active, if P1311 > 0 resp. if the conditiones given below are fulfilled.

Applies boost in [%] relative to P0305 (rated motor current) following a positive setpoint change and drops back out once the setpoint is reached. It is activated when the setpoint changes and deactivated when the setpoint is reached.
