<p>An emergency stop control circuit for controlling emergency stop signals of a numerically controlled machine tool. A relay circuit (1) has input terminals connected to all the sources of the emergency stop signals, such as an emergency stop button (22), an overload switch (33), and overtravel switches (34, 35), and further has output contacts (2a, 2b, 2c) for the required units. By simply connecting them, therefore, an emergency stop control circuit of easy connection is realized without the need for complex wiring.</p> |
