This is how you optimize the starting behavior of the V/f control for a high break loose torque and overload
Parameter
Description
p1310
Voltage boost to compensate ohmic losses
The voltage boost is active from standstill up to the rated speed.
It is at its highest at speed 0 and continually decreases as the speed increases.
Value of the voltage boost at speed 0 in V:
1.732 × rated motor current (p0305) × stator resistance (r0395) × p1310 / 100%
p1311
Voltage boost when accelerating
The voltage boost is effective from standstill up to the rated speed.
It is independent of the speed and has a value in V of:
1.732 × rated motor current (p0305) × stator resistance (p0350) × p1311 / 100%
p1312
Voltage boost when starting
Setting to additionally boost the voltage when starting, however only when accelerating for the first time.

Working with STARTER
A.5.1
Change settings
After the basic commissioning, you can adapt the inverter to your application as described in
the Commissioning guidelines (Page 83).
STARTER offers two options:
● Change the settings using the appropriate screen forms -
our recommendation
.
① Navigation bar: For each inverter function, select the corresponding screen form.
② tabs: Switch between screen forms.
If you change the settings using screen forms you do not need to know the parameter
numbers.
● You change the settings using the parameters in the expert list.
If you wish to change the settings using the expert list, you need to know the
corresponding parameter number and its significance.
