Parameter Factory Setting Description
70A 90A
MOTOR MENU
System Resistance 60 mΩ
80 mΩ
73 mΩ
Sets the system resistance (motor + brushes + wiring + con-
nections) used for load compensation and speed estimation.
Control system performance depends on this parameter
being set correctly; it must be set to the actual cold motor
resistance.
Resistance Auto Comp OFF ON
Resistance is automatically measured under a preset low cur-
rent before the brake is released. The measured motor resis-
tance plays an important role in IR compensation.
The Resistance Auto Comp parameter enables/disables this
automatic function.
Auto Comp Current
Limit
20% 20%
Sets the current limit used for automatic resistance testing, as
a percentage of the Main Current Limit (see Current menu).
Speed Scaler 27V 27V
The Speed Scaler parameter sets the maximum voltage that
can be applied to the motor. It can be used to eliminate varia-
tions in maximum speed that would otherwise result when
driving with a fully charged battery vs. a partially discharged
battery. If Speed Scaler is set to 23 volts, for example, the
maximum vehicle speed will be the same whether the actual
battery voltage is 27 volts or 23 volts or any value in between.
Current Rating 56A 25A
This parameter should be set to the current rating provided by
the motor 0–70 A manufacturer.
Max Current Time 60 sec. 120 sec.
Sets the maximum amount of time the motor is allowed to run
at the main current limit.
Cutback Gain 20% 0%
When the motor overheats, the drive current is cut back until it
reaches the programmed Current Rating. The Cutback Gain
determines how quickly this cutback will occur, once the pro-
grammed Max Current Time has expired.
BDI MENU
Full Voltage 24.4V 24.4V
Voltage when the battery is fully charged. Note: Allowable
range is restricted by the Empty Voltage, Start Charge Volt-
age, and Reset Voltage settings.
Empty Voltage 20.8V 20.8V
Voltage when the battery is fully discharged.
Note: Allowable range is restricted by the Full Voltage setting.
Full Charge Voltage 28.2V 28.2V
Voltage, when a charger is connected, above which the battery
is considered finished charging.
Note: Allowable range is restricted by the Start Charge setting.
