NetGain WarP-Drive

Using an NetGain WarP-Drive DC motor driver with an Lithiumate BMS.

A load current sensor is required when using a Warp motor driver.

Warp motor drivers MUST be used with CAN bus control (there is no way of reducing the drive without a CAN bus).

The only item that the Lithiumate BMS controls is the maximum battery current drawn by the NetGain WarP-Drive motor driver, to protect the battery.
The NetGain WarP-Drive does not offer a way to reduce the drive, neither gradually (such as by reducing the throttle range) not step-wise (such as a "valet mode"). Therefore, with this motor controller there is no way to warn the user that the battery is nearly empty, by making the vehicle feel sluggish.

Note:

• The NetGain WarP-Drive rev must be 9/28/10 or later; otherwise, the BMS is not able to control the motor controller through the CAN bus
• The Lithiumate must be configured to talk to the NetGain WarP-Drive
• The Lithiumate must be configured for 250 kHz CAN speed
• The NetGain WarP-Drive CAN port is not terminated; unless there is a termination further down the CAN bus, you must add a 120 Ohm resistor near the CAN port of the NetGain WarP-Drive
• The 2 CAN bus connectors on the NetGain WarP-Drive are identical
• In the NetGain WarP-Drive's CAN bus port, the CAN lines are on the 2 left-most pins
• In the NetGain WarP-Drive's CAN bus port, there is no need to connect the ground pin
