<p>PURPOSE:To permit the motor control having the excellent position precision by prohibiting the transmission of the next output information for a motor from a main station to a substation during a certain time when stop or reverse revolution is generated during the motor control for pulse generation and counting the pulse signals which change during this period, and transmitting the next output information to the substaion. CONSTITUTION:A main station 100 takes in the input information of substations 101-106 through a multiple signal line 130 and transmits the information to substations. A motor 210 is controlled in the normal and reverse directions by an input/output buffer 220, and a SW 201 is turned-ON/OFF according to the control, and the information is formed as pulse signal. When the demand for changing the motor 210 to the rearward direction from the normal revolution of a SW 202 to the reverse revolution of a SW 203, or SW is turned OFF after any of the forward direction and rearward direction is turned ON, the output state refuge control is performed. The waiting time is the time necessary and sufficient for the transmission of the data to the substations, and the pulse signal 201 which is changed during this period is correctly counted.</p> |
