Depending on the particu- lar characteristics of the robot workspace, the settings for the safety system must be configured to guarantee the safety of all personnel and equipment around the robot. Applying settings defined by the risk assessment is the first thing the integrator must do.

    10.2 Changing the Safety Configuration 10.2 Changing the Safety Configuration The safety configuration settings shall only be changed in compliance with the risk assessment conducted by the integrator. The recommended procedure for changing the safety configuration is as follows: 1. Make sure that the changes are in compliance with the risk assessment conducted by the integrator.

  • Page 91: Safety Modes

    10.6 Safety Modes 10.6 Safety Modes Under normal conditions (i.e. when no protective stop is in effect), the safety system operates in one of the following safety modes, each with an associated set of safety limits: Normal mode: The safety mode that is active by default; Reduced mode: Active when the robot TCP is positioned beyond a Trigger Reduced mode plane (see 10.12), or when triggered using a configurable input (see 10.13).

  • Page 93: General Limits

    10.10 General Limits Furthermore, on confirmation the changes are automatically saved as part of the cur- rent robot installation. See 13.5 for further information on saving the robot installation. 10.10 General Limits The general safety limits serve to limit the linear speed of the robot TCP as well as the force it may exert on the environment.
  • Page 94 10.10 General Limits Defining the general safety limits only defines the limits for the tool, and not the over- all limits of the robot arm. This means that although a speed limit is specified, it does not guarantee that other parts of the robot arm will obey this same limitation. When in Freedrive mode (see 13.1.5), and the current speed of the robot TCP is close to the Speed limit, the user will feel a repelling force which increases in magnitude the closer the speed comes to the limit.
  • Page 95 10.10 General Limits Maximum. The force limit can be set to a value between 100 N (50 N for a UR3) and 250 N, and the power limit can be set to a value between 80 W and 1000 W. Note that the fields for limits in Reduced mode are disabled when neither a safety plane nor a configurable input is set to trigger it (see 10.12 and 10.13 for more details).
  • Page 96: Joint Limits

    10.11 Joint Limits 10.11 Joint Limits Joint limits restrict the movement of individual joints in joint space, i.e. they do not refer to Cartesian space but rather to the internal (rotational) position of the joints and their rotational speed. The radio buttons in the upper portion of the subpanel make it possible to independently set up Maximum Speed and Position Range for the joints.
  • Page 97: Boundaries

    10.12 Boundaries The tolerance and unit for each limit are listed at the end of the row that corresponds to it. When a program is running, the speed of the robot arm is automatically adjusted in order to not exceed any of the entered values minus the tolerance (see 10.4). Note that the minus sign displayed with each tolerance value is only there to indicate that the tolerance is subtracted from the actual entered value.
  • Page 98: Selecting A Boundary To Configure

    10.12 Boundaries The configuration of each boundary limit is based on one of the features defined in the current robot installation (see 13.12). NOTE: It is highly recommended, that you create all features needed for the configuration of all the desired boundary limits and assign them ap- propriate names before editing the safety configuration.
  • Page 99: Safety Plane Configuration

    10.12 Boundaries boundary entries where the visibility toggle is selected (i.e. showing icon) in the Safety Boundaries section are displayed together with the current selected boundary limit. The (active) safety planes are shown in yellow and black with a small arrow represent- ing the plane normal, which indicates the side of the plane on which the robot TCP is allowed to be positioned.
  • Page 100 10.12 Boundaries Name The Name text field allows the user to assign a name to the selected safety plane. Change the name by tapping the text field and entering a new name. Copy Feature The position and normal of the safety plane is specified using a fea- ture (see 13.12) from the current robot installation.
  • Page 101 10.12 Boundaries The selected safety mode is indicated by an icon in the corresponding entry in the Safety Boundaries panel. If the safety mode is set to Disabled, no icon is shown. Displacement When a feature has been selected in the drop down box in the lower left portion of the Safety Plane Properties panel, the safety plane can be trans- lated by tapping the Displacement text field in the lower right portion of this panel and entering a value.
  • Page 102: Tool Boundary Configuration

    10.12 Boundaries When a transition from Reduced to Normal mode is caused by passing through a Trigger Reduced mode plane, a transition from the Reduced mode limit set to the Normal mode limit set occurs. As soon as the robot TCP passes through the Trigger Reduced mode plane, the more permissive of the Normal and Reduced mode limits is applied for each limit value.
  • Page 103 10.12 Boundaries The accepted value range together with the tolerance and unit of the deviation are listed next to the text field. Copy Feature The desired orientation of the robot tool is specified using a feature (see 13.12) from the current robot installation. The z-axis of the selected feature will be used as the desired tool orientation vector for this limit.
  • Page 104: Safety I/o

    10.13 Safety I/O 10.13 Safety I/O This screen defines the Safety functions for configurable inputs and outputs (I/Os). The I/Os are divided between the inputs and outputs, and are paired up so that each function is providing a Category 3 and PLd I/O. Each Safety function can only control one pair of I/Os.
  • Page 105 10.13 Safety I/O for more details). When this input safety function is selected, a low signal given to the inputs causes the safety system to transition to Reduced mode. If necessary, the robot arm then decelerates to satisfy the Reduced mode limit set. Should the robot arm still violate any of the Reduced mode limits, it performs a Stop Category 0.

The Base is where the robot is mounted, and at the other end (Wrist 3) the tool of the robot is attached. By coordinating the motion of each of the joints, the robot can move its tool around freely, with the exception of the area directly above and directly below the base.
