Malfunction Factors

Malfunction occurs due to two main factors:

• Controller factor: Controller needs to be reset

• External equipment factor: Operation can be resumed after a function reset.
  This occurs when a new command execution request is sent while another commad is still executing. Command processing of this function is under the premise that one command is complete by a set of request and response. If a new command request is executed while the other command is being executed, phases of the external equipment and the Controller do not match. In this case, stop the operation for safety.
