<p>PROBLEM TO BE SOLVED: To solve a problem that a situation occurs where an emergency stop switch of an operation panel is invalidated only by operating an attaching and detaching switch even in a state that a power source is turned on in the hitherto known control device.SOLUTION: A control system 100 according to the invention includes a control device 2 for controlling a drive body and an operation panel 1 having an emergency stop switch 11. The control device 2 has an emergency stop circuit 21 for stopping an operation of the drive body when the emergency stop switch 11 is operated; an attaching and detaching preparation change-over switch 23 for coming into an "attaching and detaching mode" when the operation panel 1 is attached to and detached from the control device 2 and comes into a "normal mode" in an another state; and a connection state monitoring part 24 for transmitting connection state information of the operation panel 1 to a CPU 20 or to the emergency stop circuit 21. The control device 2 invalidates an operation of the emergency stop circuit 21 when the attaching and detaching preparation information comes into the "attaching and detaching mode" and the operation panel 1 is cut apart from the control device 2.</p> |
