Fault Phenomenon: Vertech electric forklift when releasing the accelerator pedal, there is no regenerative braking effect, the vehicle coasts too long.

Troubleshooting Process:
– Checked controller parameters: regenerative braking parameter set to 0.
– Checked battery voltage: battery fully charged, cannot recover.
– Checked braking resistor: resistor open circuit.
– Checked accelerator signal: signal not at zero.

Root Cause: Incorrect setting of the controller’s regenerative braking parameter or battery is fully charged.

Required Parts: Controller parameter reconfiguration.
