SA3100 Local Tunable
Variables
C.1 Current Minor Loop Gain Variables
The stator resistance and the stator time constant values can be generated
automatically by using the enable tuning command (register 100/1100, bit 1). The
values generated by the system should not require adjustment. If any of these values
are modified outside of acceptable limits, the new value will be ignored and the last
acceptable value entered will be used. Bit 8 in warning register 203/1203 will also be
set to indicate the value entered was invalid.
CM L_WCO% Current Minor Loop Crossover Frequency
The value of the Current Minor Loop Crossover
Frequency sets the desired response of the
current minor loop. The higher the value, the
more quickly the drive responds to a change in
torque reference current. Units: Rads/Sec
Default Value: 1000
Low Limit: 1000
High Limit: 4000
Step: 1
This value is entered in radians per second. Note that if this value is adjusted too
high, the current minor loop will become unstable.
FLX_WCO% Flux Loop Crossover Frequency
The value of the Flux Loop Crossover
Frequency is used to adjust the bandwidth of
the flux loop used in the Constant Power
version of the SA3100 Vector regulator. Units: Rads/Sec
Default Value: 10
Low Limit: 5
High Limit: 50
Step: 1
The value is entered in radians per second, where 1 = 1 radian/second.
STATOR_R_E4% Stator Resistance
The value of the Stator Resistance is used to
adjust the gain of the current minor loop. It is
also used in flux feedback calculations.
The value is entered in ohms times 10000, e.g.,
a resistance of 0.1 ohm is entered as 1000.
Units: Ohms
