Figure 6-43 The resulting voltage boost using a linear characteristic as example
The inverter boosts the voltage corresponding to the starting currents p1310 … p1312.
Parameter Description
p1310 Starting current (voltage boost) permanent (factory setting 50%)
Compensates for voltage drops caused by long motor cables and the ohmic losses in
the motor.
p1311 Starting current (voltage boost) when accelerating (factory setting 0%)
Provides additional torque when the motor accelerates.
p1312 Starting current (voltage boost) when starting (factory setting 0%)
Provides additional torque, however, only when the motor accelerates for the first time
after it has been switched on ("break loose torque").
You will find more information on this function in the parameter list and in function diagram
6301 in the List Manual.
