3. If the motor does not rotate smoothly, or even remains stationary, increase the voltage boost
p1310 until the motor runs smoothly.
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.
