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 should be set to 0.
Important Note: The function is used to optimize motor and
control performance and this setting will be determined by
GE and OEM engineers at the time of vehicle development.
This setting must not be changed by field personnel without
the permission of the OEM.

FUNCTION 26
RATIO OF FIELD TO ARMATURE AMPS
This function sets the ratio between armature and field
current when transitioning from minimum field to maximum
field current. The setting represents the quantity of field
current changed for each 1 amp of armature current
changed.

This function adjusts the number of 30 second intervals
registering in the hour meter. This function is typically not
set by an OEM, it is usually only read from the register.

FUNCTION 28
POINTER
This register contains the location of the last stored status

status codes have caused a PMT controller shutdown
and/or disruption of normal vehicle operation.
