PURPOSE:To provide the driving device for a motor-operated curtain capable of stopping the motor without destroying it and stopping the substantial operation of a motor control means when the indication of opening or closing is given or kept given by a control switch under circumstances where the obstacles inhibit or inhibited the operation of the curtain. CONSTITUTION:A function detects a speed exceeding the prescribed high-speed and turns off a power supply switch 2 and when it is outputted to a motor control means 10 having an arithmetic processing part 14, it calculates a command value based on the setting speed, detection speed, and control coefficient so that the detection speed is nearly matched with the setting speed in controlling a motor 7, and when detecting it, curtain is stopped and a power supply switch cutting signal is outputted from the function. |
