FUNCTION 8 FIELD WEAKENING DROP OUT
( Push 8 )
This function allows for the adjustment of the field weaken-
ing contactor drop out current. This setting allows the FW
contactor to drop out when the vehicle requires greater than
300% of the full load level running current for greater
torque.
Range 65 to 895 amps (EV100)
98 to 1343 amps (EV200)
Set 0 to 255
Resolution 3.25 amps per set unit (EV100)
4.88 amps per set unit (EV200)
Example Setting of 20 = 130 amps
FUNCTION 9 REGEN BRAKING C/L
( Push 9 )
This function allows for the adjustment of the Regen braking
current limit. The higher the current the shorter the stopping
distance.
Range 75 to 630 amps
Set 0 to 255
Resolution 2.2 amps per set unit
Example: Setting of 20 = 119 amps
FUNCTION 10 REGEN START
( Push 10 )
This function allows for the adjustment of the percent on
time at which the control will start to regen. Adjustment of
this function allows the OEM to set the regen start speed of
the vehicle to eliminate regen attempts when motor regen
current is low.
Range 0 to 95% on time
Set 0 to 255
Resolution .37% per set unit
Example: Setting of 20 = 7.4% on time
FUNCTION 11 SPEED LIMIT 1 (SL1)
( Push 11 )
This function allows for the adjustment of the speed limit (
maximum battery volts to the motor ) when the SL1 limit
switch input signal is received by the control card. SL1 limit
switch is a normally closed switch connected to battery
negative, the switch opening enables speed limit.
Range 96% to 0% battery volts
Set 0 to 180
Setting of 0 set units will disable speed limit function and
allow top speed with no limit switch connected.
FUNCTION 12 SPEED LIMIT 2 (SL2)
( Push 12 )
Same as Function 11 except using SL2 limit switch for input.
FUNCTION 13 SPEED LIMIT 3 (SL3)
( Push 13 )
Same as Function 11 except using SL3 limit switch for input.
The SL3 set speed limit is also activated by the Truck
Management Module fault codes 90 and 93. See instructions
for IC3645TMM1A Truck Management Module for details.
FUNCTION 14 INTERNAL RESISTANCE
COMPENSATION
( Push 14 )
This function is used when the Battery Discharge Indicator
is present. Adjustment of this function will improve the
accuracy of the BDI. In order to made this setting the voltage
drop of the battery under load must first be determined by
following the steps listed below.
1. Load the traction motor to 100 amps in 1A and
record the voltage (V
O
) at the SCR positive and
negative power terminal.
2. Load the traction motor to 200 amps in 1A and
record the voltage (V
L
) at the SCR positive and
negative power terminal.
3. Calculate voltage drop (V
D
) as follows:
V
D
= V
O
- V
L
4. Use the table below to determine the setting using
the calculated V
D
as a reference.

FUNCTION 15 BATTERY VOLTS
( Push 15 )
This function allows for the adjustment of voltage range for
controls equipped with the Battery Discharge Indication
function. In order for the BDI to operate properly, the setting
