Regeneration Check
The AC motor uses a common circuit for current flow in both loading and regeneration. This allows the following procedure to confirm regeneration.
1. Place the clamp ammeter onto the cable connected to the inverter’s F terminal (use DC current range). This is positive direction as current flows from the battery to the inverter.
2. Run the truck forward. With the direction lever shifted in F position, release the accelerator pedal. Then perform a full-reverse operation.
3. The clamp ammeter should show a negative value. This value becomes the regeneration current.

Energy is generated when a motor is rotated with external force. The regeneration power is produced when this energy is larger than the one that is consumed by the controller and motor. This means that the regeneration current is not measured if the speed or load changes gradually.
