SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Sets V/f coordinates (P1320/1321 to P1324/1325) to define V/f characteristic.
These parameter pairs can be used to provide correct torque at correct frequency and is useful when used with
synchronous motors. Parameter P1320 defines the frequency of the first point of the characteristic.
Dependency: To set parameter, select P1300 = 3 (V/f with programmable characteristic).
The acceleration boost and starting boost defined in P1311 and P1312 are applied to V/f with programmable char-
acteristic.
Note: Linear interpolation will be applied between the individual data points.
V/f with programmable characteristic (P1300 = 3) has 3 programmable points and 2 non-programmable points.
The 2 non-programmable points are:
• Continuous boost P1310 at 0 Hz
• Rated motor voltage P0304 at rated motor frequency P0310
