as a reference.
This function adjusts the gain on the filed ramp rate when
the speed error is less than 1 MPH
. This function is used
only when Mode 0 is selected.

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 20
TOP SPEED REGULATION SPEED
This function adjusts the value of the top speed point of the
control around which speed regulation occurs.
Resolution
0.1MPH per set unit
Example:
Setting of 100 = 10.0 MPH
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 21
FIELD CURRENT RAMP DURING PEDAL
UP REGEN
In order for the battery discharge indication feature of this
control to operate properly, this function must be set to a
value between ____ and ____ for a 48V battery.
This function adjusts the rate at which the field current
ramps when the start switch is opened.
This function is
used only when Mode 0 is selected.

the permission of the OEM.
This function is not applicable to this control type.
FUNCTION 18
FIELD GAIN 2
This function adjusts the gain on the filed ramp rate when
the speed error is greater than 1 MPH .
This function is
used only when Mode 0 is selected.
FUNCTION 22
NOT APPLICABLE
This function is not applicable to this control type.
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 23
ERROR COMPENSATION
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.
