| 0 | Controller over votlage | 1,1 | The filtered battery voltage measurement has exceeded the Slow over voltage threshold for greater than 1 second. The motor phase bridge is disabled. | battery voltage is less than Slow over voltage threshold for more than 1 second. | This fault cannot be disabled and can only be set out of the way. It can be set up to the limit of the controller input rating. Set Slow over voltage threshold far above potential battery voltage values. | Set the Rated system voltage to the battery’s nominal voltage. Verify the Slow over voltage threshold is set appropriately. |
| 1 | Phase over current | 1,2 | The motor phase current measurement has exceeded the Averaged over current trip threshold for the number of samples specified by Averaged overcurrent trip sample length. The motor phase bridge is disabled. | Reboot the controller or send a fault reset command. | Averaged overcurrent trip threshold and Averaged overcurrent trip sample length are manufacturer-level parameters. These parameters cannot be changed to disable this fault. | Adjust the Current regulator bandwidth down to balance the controller’s current response with minimized phase current spikes. Reduce the Rated motor current to reduce potential phase current peaks. A higher amperage-capable controller should be considered. Verify there are no intermittent short circuits between the phases and battery terminals. |
| 2 | Current sensor calibration | 1,3 | The phase A current sensor offset or phase C current sensor offset calibration of the current sensors has failed. The current sensor calibration reading at bootup is off by greater than 5%. The nominal value is 50%. The motor phase bridge is disabled. | Reboot the controller | Cannot be disabled. | Eliminate possible magnetic fields. If the fault doesn’t clear after rebooting and removing possible magnetic field effects, contact ASI for support. |
| 3 | Current sensor over current | 1,4 | Current sensor built-in hardware overcurrent fault protection tripped due to an application over current or a current sensor failure.

The motor phase bridge is disabled. | Reboot the controller or send a fault reset command. | Option 1 – Change Motor position sensor type from Hall based to Hall start and sensorless run, enable Motor features bit 1 Fault tolerant hall to switch immediately to sensorless from Hall when a fault is detected. Option 2 – Change Motor position sensor type to sensorless mode. | Option 1 – Redo the motor discovery, the Hall table may be bad. Option 2 – Set up your motor to run efficiently in sensorless mode and then switch the Motor positiong sensor type to Hall start and sensorless run. Option 3 – Verify your Halls with an oscilloscope to ensure they are operating as expected and the noise is not forcing unexpected state change measurements on the controller side. |
| 6 | Controller under voltage | 1,7 | The filtered battery voltage measurement has dropped below the Slow under voltage threshold for greater than 1 second. The motor phase bridge is disabled. | battery voltage is greater than threshold for more than 1 second, the fault will clear. | This fault cannot be disabled and can only be set out of the way. Set the Slow under voltage threshold far below potential battery voltage values. | Verify the Rated system voltage is set to the battery’s nominal voltage.

The motor phase bridge is disabled. | Reboot the controller or send a fault reset command. | Cannot be disabled. | Disconnect the 3 phase wires from the controller. If disonnecting the 3 phase wires and rebooting clears the fault, the problem is in the motor or wiring harness. There may be a short through the motor or phase harness to battery, or the motor sensors. This can sometimes happen due to water ingress into the motor. If disconnecting the motor phases from the controller does not clear the fault, contact ASI for support. |
| 8 | Network communication timeout | 2,1 | The controller has not received a new heartbeat value on Remote state command high byte over an elapsed time that exceeds the Command timeout threshold (1 sample) or the Average Command timeout threshold (100 samples) when either in remote control, Control command source set to serial stream and Remote state command is set to 2 (Run), or within the CAN sync loss timeout, or when Throttle sensor source is set to 5 (network voltage) and Remote throttle voltage is within the throttle window to active the bridge. The motor phase bridge is disabled. | Reboot the controller or send a fault reset command. | Set Command timeout threshold and Average Command timeout threshold to 0. | Set Command timeout threshold and Average Command timeout threshold appropriately to capture faults but but not trigger nuisance trips from occasionally missed packets.
