However priorities are allocated to these parameters as follows:
P1310 > P1311 > P1312
Notice:
Increasing the boost levels increases motor heating (especially at standstill).

P-Group: CONTROL Active: Immediately QuickComm. No Max: 250.0
P1311 will only produce boost during ramping, and is therefore useful for additional torque during
acceleration and deceleration.
Applies boost in [%] relative to P0305 (rated motor current) following a positive setpoint change and drops
back out once the setpoint is reached.

where voltage values are given
V_AccBoost,100 = rated motor current (P0305) * Stator resistance (P0350) * Acceleration boost (P1311)
V_AccBoost,50 = V_AccBoost,100 / 2
Dependency:
Setting in P0640 (motor overload factor [%]) limits boost.
Note:
Acceleration boost can help to improve response to small positive setpoint changes.
