CP-Parameter for open-loop operation
CP16 Rated frequency
Co-domain Setting Description
0.00…400.00 Hz 50 Hz With the adjusted frequency the inverter reaches in controlled
operation a maximal output voltage. The adjustment of the rat-
ed motor frequency is typical in this case.
Attention
In order to drive dened ramps with ac-
tivated S-curve time, the preset accel-
eration and deceleration times (CP12
and CP13) must be adjusted higher
than the S-curve time (CP14).

CP16
CP17 Voltage stabilization
Co-domain Setting Description
1…650 V (off) 650 V (off) With this parameter a regulated output voltage in relation
to the rated frequency can be adjusted. For that reason
voltage variations at the input as well as in the intermedi-
ate circuit only have a small inuence to the output volt-
age (U/f-characteristic). The function allows an adaption
of the output voltage to special motors. The values must
be conrmed with „ENTER“.
In the example below the output voltage is stabilized to
230 V (0 % boost).
