In applications with a high break loose torque, you must also increase parameter p1312 in
order to achieve a satisfactory motor response.
You have set the voltage boost.

The resulting voltage boost using a linear characteristic as example
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").
