Boost input at function block LS_MotorInterface (from V4.0 onwards)

Function extension:
The boost input of the function block 'LS_MotorInterface' can be used to increase the motor voltage from outside during operation. To do this, a corresponding process signal must be applied to the 'nBoost_a' input.

Applications
Increase in the motor voltage by means of a process signal (16384  1000 V) in order to achieve a higher starting torque for the 'V/f characteristic control' (VFCplus) operating mode. This can be done by means of a control unit or a function block interconnection, for example. This signal also serves to increase Vmin (L-C00016).
