Setting sequence

1.If necessary, select V/f

characteristic with auto boost
(C014 = -0- or -1-).

2.Select V/f-rated frequency

(C015).

-

The V/f-rated frequency determines the slope of the V/f characteristic and has considerable
influence on the current, torque and power performance of the motor.

-

An internal mains voltage compensation compensates deviations in the mains during operation.
Therefore, they do not have to be considered for the setting of C015.

-

Use standard motors with 230/400 V with

a connection, since with an input voltage of 230 V a

max. of 3AC 230 V is at the output.
