D CURRE

ARMATURE CURRENT

The

" minimum field

current"

setting is adjusted

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

The

" maximum field current"

setting is adjusted by Function 8. This
function, along with the

"armature

current limit",

Function 4

sets the

maximum torque of the motor.

The

"armature current limit"

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 be
achieved .

The

" ratio"

setting is adjusted by Function 26.

This function sets the ratio between armature
and field current when operating, I

MOTOR

above FWS and less than 300 amps. 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 300A armature
current.

The

" error compensation "

setting is adjusted by

Function 23. 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.

Maximum field

current is fixed at

37.5 amps
