Abstract: PURPOSE:To enable a user to contact the system at all times. CONSTITUTION:A man-machine interface(MMI) task 1 interprets a command group from an engineering work station(EWS), etc., and requests a communication control task 2 to execute the commands. The communication control task 2 repeats the command execution request from the MMI task 1 to an object process task 3. At this time, the object process task 3 decides whether or not the commands can be executed and repeats the command execution request to the object process task 3 when the decision result is affirmative. If, however, the object process task 3 is in the execution of, for example another process and the decision result is inaffirmative, information such as a message indicating that is sent back to the MMI task. The object process task 3 receives the command execution request from the communication control task 2 and performs specific processes corresponding to the commands. The tasks 1-3 are provided by a multi-task function and put in parallel operation.

Abstract: PURPOSE: To prevent a malfunction by masking the decision of an insertion decision means with a mask means on the basis of the angle of rotation with motor start and properly maintaining the mask time in response to rotational speed at the time of motor start. CONSTITUTION: The twist of a rubber damper for a motor armature and a looseness phenomenon such as play between gears are utilized and a mask value is set in the unstable operating time at the time of the start of a motor M. A computer 60 inhibits the decision of the presence of the insertion of a foreign matter at the time of the start of the motor M by the mask value. The mask value is specified by a pulse number by the looseness phenomenon, a fixed angle of rotation after the start of the motor M, not rotational speed at the time of the start of the motor M at that time. The mask time is maintained properly in response to the rotational speed of the motor M.  The decision of the presence of the insertion of the foreign matter between unstable operation at the time of the start of the motor M is suppressed by the mask time corresponding to rotational speed at the time of the start of the motor M. Accordingly, the malfunction of the decision of insertion at the time of start can be prevented.
