Section 6.5 Summary of Current Limit Adjustments

ZERO

MAXIMUM

ZERO

MAXI

ELD CURRENT

ARMATURE CURRENT

The

" minimum field

current"

setting is adjusted

by Function 7. The function
sets the top speed of the
motor.

The

" maximum field current"

setting is adjusted by Function 8.

This function, along with the

"maximum armature current"

(Function 4), sets the maximum

torque of the motor.

The

" maximum armature

current"

setting is adjusted by

Function 4. The function along with

the

"maximum field current"

(Function 8) sets the maximum

torque of the motor.

The

" field weakening start "

setting is adjusted by Function 24.

This function sets the armature

current at which minimum field

current will achieved .

The

" ratio"

setting is adjusted by Function 26.

This function sets the ratio between armature

and field current when transitioning from

minimum field to maximum field current. Setting

is the value of field current changed for each 100

amps of armature current changed.

The

"full load transition point"

is calculated by the control.

This

function sets the maximum field

current transition point at

approximately 80% of the

maximum armature current.

The

" error compensation "

setting is adjusted by

Function 27. This function is used to reduce the ripple
in field current due to the interaction between motor
field design and the digital field current regulation
circuit. The value for this function will be defined by the
GE application engineer.
