4. Accelerate the motor to the maximum speed with maximum load.
5. Check that the motor follows 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 also increase parameter p1312 in
order to achieve a satisfactory motor response.
You have set the voltage boost.

Maximum output voltage [V]
Rated motor frequency [Hz]
Starting current (voltage boost)
permanent [%]
Starting current (voltage boost)
when accelerating [%]
Starting current (voltage boost)
when starting [%]
Setting
Displays the maximum output voltage.
Sets the rated motor frequency.
Factory setting: 0
Defines the voltage boost as a [%] referred to the
rated motor current (p0305).
Factory setting: 50
p1311 only results in a voltage boost when accel-
erating and generates a supplementary torque to
accelerate the load.
Factory setting: 0
Setting for an additional voltage boost when
powering-up, however, only for the first accelera-
tion phase.
Factory setting: 0
