CUT

Datatype: Float

Unit: %

Def:

P-Group:

CONTROL

Active: Immediately

QuickComm.: No

Max:

100.0

Level

3

Defines point at which programmed boost reaches 50 % of its value. This value is expressed in [%] relative to P0310 (rated motor frequency).

The default frequency is defined as follows:

fBoostmin = 2 ( 153 + 3)

Index:

P1316[0] : 1st. Drive data set (DDS)

P1316[1] : 2nd. Drive data set (DDS)

P1316[2] : 3rd. Drive data set (DDS)

Note:

-The expert user may change this value to alter the shape of the curve, e.g. to increase torque at a particular frequency.

-Default value is depending on inverter type and its rating data.

Details:

See diagram in P1310 (continuous boost).

Example:

This parameter can be used to provide correct torque at correct frequency and is useful when used with synchronous motors.

Dependency:

To set parameter, select P1300 = 3 (V/f with programmable characteristic).

Note:

Linear interpolation will be applied between the individual data points.

V/f with programmable characteristic (P1300 = 3) has 3 programmable points. The two non-programmable points are:

-Continuous boost P1310 at zero 0 Hz

-Rated motor voltage P0304 at rated motor frequency P0310

The acceleration boost and starting boost defined in P1311 and P1312 are applied to V/f with programmable characteristic.
