FUNCTION 21
AUTO REGEN BRAKING C/L
(Push CONT 6)
This function allows for the adjustment of the Regen braking
current limit. The higher the current the shorter the stopping
distance.

FUNCTION 25
MONITOR
( Push CONT 10)
This function allows the monitoring of certain control
functions by looking directly at the RAM of the
microprocessor. Because absolute memory locations need
to be known, this function should not be used without
detailed instructions from the GE application engineer.
This function should only be adjusted by the vehicle OEM.
To ensure optimum operation of the control, this function
must be left with zero stored in this register.
FUNCTION 26
RATIO
( Push CONT 11)
This function sets the ratio between armature and field
current when operating below the maximum field current
and above the Field Weakening Start point. The setting
represents the quantity of field current changed for each 1
amp of armature current changed.
