Speedregulation Gain Calc Control (Spdreg Gain Calc); Constant V/F " Control (V/F Config) - GE AV-300i User Manual

1.3.2.5 SpeedRegulation Gain Calc Control (SpdReg Gain Calc)

The Function is active only in a Sensorless or Field oriented mode. It allows Speed regulator Gain calculation.
First, load inertia must be entered into the Calc Inertia parameter. Load inertia is either known application
parameter or it can be obtained by using Speed regulator autotune procedure.
With Calc method parameter two gain calculation methods can be selected:
Variable bandw resulting speed regulation bandwidth is internaly selected according to the principle that
bandwidth is decreased as inertia is increased and vice versa.
Fixed bandw resulting speed regulation bandwidth is specified by parameter Bandwidth
N !
OTE
Parameters Calc method and Bandwidth are also valid for Speed regulator autotune procedure.

Type of load
Constant torque requirement across the whole speed range
Mixed load between types 0 and 3
Mixed load between types 0 and 3
Load where the torque is proportional to the speed squared,
e.g. fans and certain types of pump
Discharge starting voltage for the V/f mode
Discharge starting frequency for the V/f mode
V/F Curve shape. It can be selected among:
Type 0 V/f ^ 1.0 (use this selection for loads with a constant torque)
Type 1 V/f ^ 1.5
Type 2 V/f ^ 1.7
Type 3 V/f ^ 2.0
