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)

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
-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.
