DESCRIPTION
Battery Voltage
1 – 6
Set this parameter to match the battery pack of your vehicle.
1 = 12 V
2 = 24 V
3 = 36 V
4 = 48 V
5 = 60 V
6 = 72 V.
Under Voltage Cutback
68 – 100 %
The controller’s circuitry requires a minimum battery voltage to function
properly. When battery voltage drops, reducing the controller’s output
to the motor allows the battery to recover. The Under Voltage Cutback
parameter sets the threshold voltage below which controller output will
start to be reduced.
The programmed value is a percentage of the battery voltage.
Under Voltage Cutback Rate
0 – 110 A
The Under Voltage Cutback Rate determines how quickly the controller
output will be reduced when battery voltage falls below the programmed
Under Voltage Cutback threshold.
The programmed value is the amount the current will be reduced
for every 0.4 V the battery voltage decreases.
Larger values represent faster reduction of controller output.
Setting Under Voltage Cutback Rate = 0 means there will be no
undervoltage cutback.
Under Voltage Cutoff
67 – 100 %
The Under Voltage Cutoff parameter sets the voltage at which controller
output will be cut off completely.
The programmed value is a percentage of the battery voltage. The
Under Voltage Cutoff parameter can only be set to values smaller (lower)
than the programmed Under Voltage Cutback.
