6.5 Motor control
5. Check whether the motor is following the setpoint.
6. If necessary, increase the voltage boost p1311 until the motor accelerates without
problem.
In applications with a high break loose torque, you must additionally set parameter p1312
higher to achieve a satisfactory response.
You have set the voltage boost.

Description
Starting current (voltage boost) permanent (factory setting 50 %)
Compensates for voltage drops caused by long motor cables and the ohmic losses in
the motor.
Starting current (voltage boost) when accelerating (factory setting 0 %)
Provides additional torque when the motor accelerates.
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").
