Speed Limit Pot
A speed limit pot allows the operator to adjust the vehicle speed. A 100kΩ pot is recommended.
If you are using a speed limit pot, perform the following steps.
1. Wire the speed limit pot to pin J3-6.
2. Set the Speed Limit Pot parameter to on. See page 34.
Note: If you are not using a speed limit pot, set this parameter to o.
3. Specify the Analog port with the Speed Limit Source parameter; see page 49.
Note: e Analog 2 port is typically used for the speed limit pot.
e following considerations apply to the speed limit pot:
• When the speed limit pot is in its maximum speed position, the vehicle’s speed at full
throttle corresponds to the speed mode’s maximum speed settings.
• When the speed limit pot is in its minimum speed position, the vehicle’s speed at full
throttle corresponds to the speed mode’s minimum speed settings.
• e speed limit pot changes the vehicle speed linearly over the range between the minimum
and maximum speed settings for the active speed mode.
Keyswitch
e keyswitch input is connected to pin J3-1. Table 17 describes the specications for the keyswitch
input.
Table 17 Keyswitch Input Specifications
Specication Value
Maximum Input Current 8A (maximum pin rating)
Maximum Voltage 150% of nominal battery voltage
Maximum Reverse Voltage –(150% of nominal battery voltage)
Quiescent Current 75mA maximum
Note: This is at nominal voltage and does not include
current draw from coil loads or external power supplies.
