Selecting the soft starting function.
Level

With soft starting, the flux in the motor is established with some delay. This ensures that the motor only rotates in the required direction of rotation even with existing residual magnetism. When activated, at

Note:
The settings for this parameter bring benefits and drawbacks:
-P1350 = 0: (jump to boost voltage)
Benefit: flux is built up quickly
Drawback: motor may move
-P1350 = 1: (smooth voltage
Benefit: motor less likely to move
Drawback: flux
