    7 Error codes and troubleshooting Actuator malfunction can be caused either by a faulty motor or faulty driving electronics. Use the s2terminal, the drivemotor command, with suitable parameters, to check the status of the motors. If there is no motion the faulty component can be easily found by replacing them one by one, the motor, the driving electronics and then the cabling until the faulty component is identified.
