Description6 Product Specification IRB 4400 M98A/BaseWare OS 3.22.2 Safety/StandardsThe robot complies fully with the health and safety standards specified in the EEC’sMachinery Directives as well as ANSI/RIA 15.06-1992.The robot is designed with absolute safety in mind. It has a dedicated safety systembased on a two-channel circuit which is monitored continuously. If any componentfails, the electrical power supplied to the motors shuts off and the brakes engage.Safety category 3Malfunction of a single component, such as a sticking relay, will be detected at the nextMOTOR OFF/MOTOR ON operation. MOTOR ON is then prevented and the faultysection is indicated. This complies with category 3 of EN 954-1, Safety of machinery -safety related parts of control systems - Part 1.Selecting the operating modeThe robot can be operated either manually or automatically. In manual mode, the robotcan only be operated via the teach pendant, i.e. not by any external equipment.Reduced speedIn manual mode, the speed is limited to a maximum of 250 mm/s (600 inches/min.).The speed limitation applies not only to the TCP (Tool Centre point), but to all parts ofthe robot. It is also possible to monitor the speed of equipment mounted on the robot.Three position enabling deviceThe enabling device on the teach pendant must be used to move the robot when in man-ual mode. The enabling device consists of a switch with three positions, meaning thatall robot movements stop when either the enabling device is pushed fully in, or when itis released completely. This makes the robot safer to operate.Safe manual movementThe robot is moved using a joystick instead of the operator having to look at the teachpendant to find the right key.Over-speed protectionThe speed of the robot is monitored by two independent computers.Emergency stopThere is one emergency stop push button on the controller and another on the teachpendant. Additional emergency stop buttons can be connected to the robot’s safetychain circuit.Safeguarded space stopThe robot has a number of electrical inputs which can be used to connect external safetyequipment, such as safety gates and light curtains. This allows the robot’s safetyfunctions to be activated both by peripheral equipment and by the robot itself.Delayed safeguarded space stopA delayed stop gives a smooth stop. The robot stops in the same way as at a normalprogram stop with no deviation from the programmed path. After approx. one secondthe power supplied to the motors shuts off.
