Descriptions
7000-TD002A-EN-P – September 2007
Flux Current Feedforward [FluxCur Feedfwd]
Linear Number:
308
Minimum Value:
-2.000 pu
Maximum Value: 2.000 pu
Access Level:
Advanced
Read/Write:
Read
Only
This parameter specifies the feed-forward component of the magnetizing or D-axis stator current
command. It is an estimate of the steady state D-axis current and is always positive. This value should
represent the baseline magnetizing current of the motor, determined from the Magnetizing Inductance of
the motor.
Flux Current Regulator [FluxCurRegulator]
Linear Number:
309
Minimum Value:
-2.000 pu
Maximum Value: 2.000 pu
Access Level:
Advanced
Read/Write:
Read
Only
This parameter specifies the closed loop correction component of the magnetizing or D-axis stator
current command. It is the output of the flux regulator and may be positive or negative. This is the
correction to the magnetizing current based on the operating conditions of the motor.
Inverter Flux Current Command [Inv Flux CurCmd]
Linear Number:
312
Minimum Value:
-2.000 pu
Maximum Value: 2.000 pu
Access Level:
Advanced
Read/Write:
Read
Only
This parameter specifies the magnetizing current command for the inverter obtained from
Mtr Flux
CurCmd
(310) and a motor filter capacitor model. It is positive for lagging current and negative for
leading current.
Alpha Inverter [Alpha Inverter]
Linear Number:
328
Minimum Value:
-360.0 deg
Maximum Value: 360.0 deg
Access Level:
Advanced
Read/Write:
Read
Only
This parameter specifies the inverter firing angle relative to the measured motor flux. It is calculated from
the torque component of the inverter output current
InvTorque CurCmd
(294
)
and the flux component of
the inverter output current
Inv Flux CurCmd
(312).
