0x3170 0x00
On / Off
On / Off
When this parameter is programmed On, the distance variables (Vehicle
Odometer, Braking Distance Captured, Distance Since Stop, Distance Fine,
and the Capture Distance variables) will accumulate and display in metric
units (km, meters, or decimeters). When programmed Off, the distance
variables will accumulate and display in English units (miles, feet, or inches).
Distance variables are displayed in the Monitor »Vehicle menu
Speed to RPM
Speed_to_RPM
0x304C 0x00
10.0 – 3000.0
100 – 30000
This parameter affects the vehicle speed displayed in the Monitor » Vehicle
menu and also modies the VCL variable Vehicle_Speed; it does not affect
actual vehicle performance. The value entered for Speed to RPM is a
conversion factor that scales motor speed to vehicle speed.
KPH to RPM: (G/d)*5305, where G = gear ratio, d = tire diameter [mm].
MPH to RPM: (G/d)*336.1, where G = gear ratio, d = tire diameter [in].
Capture Speed 1
Capture_Speed_1
0x3079 0x00
0 – 10000 rpm
0 – 10000
The controller captures the time it takes the motor to go from 0 rpm to
the programmed Capture Speed. The result is stored as “Time to Speed
1” in the Monitor » Vehicle menu. This timer starts every time the motor
accelerates from zero speed.
Capture Speed 2
Capture_Speed_2
0x3886 0x00
0 – 10000 rpm
0 – 10000
This parameter allows a second capture speed to be dened, and works
identically to Capture Speed 1. The result is stored as “Time to Speed 2” in
the Monitor » Vehicle menu.
Capture Distance 1
Capture_Distance_1
0x307A 0x00
1 – 1320
1 – 1320
The controller captures the time it takes the vehicle to travel from 0 rpm
to the programmed Capture Distance. The result is stored as “Time to Dist
1” in the Monitor » Vehicle menu. This timer starts every time the vehicle
accelerates from zero speed.
NOTE: For accurate distance measuring, the Speed to RPM parameter must
be set correctly.
With the Metric Units parameter programmed Off, distance is in units of
feet. With Metric Units programmed On, distance is in units of meters.
Capture Distance 2
Capture_Distance_2
0x3883 0x00
1 – 1320
1 – 1320
This parameter allows a second capture distance to be dened, and works
identically to Capture Distance 1. The result is stored as “Time to Dist 2” in
the Monitor » Vehicle menu.
Capture Distance 3
Capture_Distance_3
0x3884 0x00
1 – 1320
1 – 1320
This parameter allows a third capture distance to be dened, and works
identically to Capture Distance 1. The result is stored as “Time to Dist 3”in
the Monitor » Vehicle menu.

BATTERY: BATTERY POWER LIMITING
PARAMETER ALLOWABLE RANGE DESCRIPTION
Drive Power Limit
Battery_Drive_Power_Limit
0x31EB 0x00
0.00 – 300.00 kW
0 – 30000
Sets a limit on the DC power that the controller will draw out of
the battery during drive. Battery Current Limiting must be enabled
for Battery Power Limiting to function. The controller will use more
restrictive of this or battery current limit.
Regen Power Limit
Battery_Regen_Power_Limit
0x31EC 0x00
0.00 – 300.00 kW
0 – 30000
Sets a limit on the DC power that the controller will put into the
battery during regen. Battery Current Limiting must be enabled for
Battery Power Limiting to function. The controller will use more
restrictive of this or battery current limit.
Voltage Filter
Battery_Power_Limit_Voltage_Filter
0x31ED 0x00
0.02 – 99.5 Hz
66 – 32767
Sets the low pass lter cutoff frequency for the battery voltage
measurement used in the battery power calculation. Lower values will
lter the voltage signal more.
