- PolyScope/controller: 19293
- Manual:?19236
?
Key features:
URScript:
- Added script function "position_deviation_warning" which allows the user to identify elements of a program where the robot cannot follow the trajectory. These program elements can then be modified to reduce the risk of C153A# protective stops induced by position deviation.
?
Bug fixes
Controller:
- Fixed issue where the length of a string did not return correct value

Safety System
As part of Universal Robots ongoing work to improve the safety systems, a rare situation where the robot in a high-speed clamping situation in combination with using the "force()" script function to conditionally stop the robot, could stop and engage the brakes while contacting the clamped part, and thereby delivering slightly higher force than specified by the safety settings, has been identified. To alleviate this problem, minor changes to the safety system has been made, which can affect existing robot installations when upgrading to SW3.2. In practice, the overall sensitivity of the robot has been increased to outside force. In some applications this can cause problems with protective stops. In that case two possible workarounds can be used:
- If allowed by the safety assessment of the installation, the force limit in the safety settings can be increased. We recommend doing so in steps until the issue is resolved. No more than 25N should be necessary to resolve it
- If the safety assessment does not permit increasing the force limit safety setting, the speed and/or acceleration in the movements causing problems can be lowered
This feature was also implemented in the last bugfix release of SW3.1, rev. 18024
Manual
- Fixed an issue that caused the wrong content to be included in some parts of the PolyScope help.
- Clarified that servoj is a blocking function.

- Fixed an issue that might cause the robot to not reach a target position in conveyor tracking mode when using the speed slider
- Fixed bug that the warning C103A1 "UR Ethernet Error:3 packages in a row lost from Safety Control Board" appeared 3 times when the robot was booted. The error now only appears if the connection is broken due to an error
- Fixes issue that the Robot Not Stopping Output?is activated by Protective Stops. It is now only activated by Safeguard or Emergency Stops
- Extended sanity check with checks for Not a Number (NaN) in target setpoints. This might show as C204A5

- Added sanity check that verifies that too big changes in speed are not allowed, this may cause protective stops (code C204A3)
- Fixed an issue where the safeguard stop reset also resumed a paused program
- Corrected the description for set_standard_digital_out()
- I/O actions can now resume a paused program by activate the assigned play I/O
- Fixed an issue with the speedl script function that would cause the robot to make wrong accelerations when chaining multiple speedl commands
- Fixed an issue with socket_ascii_float() script function regarding spaces after the digit
- After position deviation failure has been detected at start up, the controller keeps generating protective stop until the user has confirmed that the position of the robot is correct
- Robot retracts approx. 10 mm at protective stop, to avoid clamping
- Fixed Protective Stops occurring when returning from force mode
- Fixed Protective Stops occurring when stopl() was used at higher speeds
- Fixed jerks occurring when using speedl() script commands
- Fixed bug with robot jerking when stopping a program while conveyor tracking
- Fixed Safety Fault C203A0 when returning from Expert mode/LowLevelControl
- Fixed issue where robot would move slower than allowed by the joint speed, TCP speed and momentum limits defined for Normal mode after disabling a Trigger Reduced mode plane

- Fixed comparison between strings
PolyScope
- Waypoints now move along with a variable feature even if the Variable check box on the feature is unset and set after the waypoints were defined
- Fixed problem with loading SW3.0 programs that contain Euromap67 program nodes.
- Cancelling the renaming of a point feature to the name of another feature no longer causes the original name to change
- Touch screen keyboard missing on entering IP address in Dual Robot Calibration?
- Issue on UR3 where dialog appears stating safety configuration corrupted on startup
- Changed the dashboard servers "savelog" behavior so it replies "Log?saved?to disk"?when it has saved the log.
- Fixed syntax error using waitForItem node with Euromap67
- Fixed the syntax error using I/O action starting a program. This occurred when the first move was defined as a variable or relative waypoint
- Fixed user interface problem on the run program tab when loading a program with a long name
- Fixed problem that prevented correct saving of subprograms even though the "keep subprogram updated with this file"-setting was checked
- Fixed issue with the "English programming" setting
- Non-variable features can again be selected in the Move node
- An edited installation variable value is now correctly initialized when the program is next run
- Copying a freshly create pallet node/a pallet node without waypoints will no longer cause an exception
- The selections in the "I/O tab control" drop-down menus in the I/O Setup screen are now correctly saved inside the installation
- Dashboard server:
- A new user role "restricted" (for the 'setUserRole' Dashboard server command) has been introduced. The role is similar to "operator", but the new role also prevents access to the Move tab
- The user interface now goes back to the Welcome screen whenever the user role has been changed
- The dashboard server has been extended with a "freedrivemode" command that can be used to restrict the use of the freedrive button, so that it may only be used in reduced mode. The restricted freedrive button mode works with the button on the teach pendant and with any external freedrive button configured in I/O setup
- Added a new screen in PolyScope to allow visual verification of the position of the robot at startup after position deviation failure. The new screen is shown at power on and replaces a protective stop popup
- Demoted warning 50A83 to info level. For instance, on applying new safety settings this message would wrongfully show up as a warning in the PolyScope log
- Fixed bug that undefined Waypoints were overwritten in French language, new name is "PointPassage"
- English only: In log messages removed the words "error" and "broken" from warning messages (in cases where the system will remain operational anyway). In the PolyScope log the info/warning/fault icons indicate the true severity of the reported issue
- English only: In log messages renamed "Masterboard" to "Safety Control Board" and "PC" to "Controller" for a few error codes
- The Waypoint named "Waypoint" inside Seek-nodes is now named "Exit"

- Euromap67 signal names are now saved in a language-independent manner. (If there is a problem with loading a program with Euromap67 signals after the language has been changed, the program first needs to be loaded and saved in the original language, then it can be loaded in any language)
- Program tab: Variable no longer disappears from the program when a node that uses a variable is removed or suppressed
- Program tab: Prevented an exception occurring after pasting a node with a variable that is not used elsewhere in the tree
- Boundaries tab: Fixed bug where validation of input for the "Deviation" text field in the configuration of the Tool Boundary was missing
Joint firmware
- Minor reduction of vibrations primarily on UR3's
- Joint: Added sanity check verifying that target speed matches changes in target positions. If not, the target speed is set to 0, and a warning C205A0 is reported
- Reduced occurrences of Faults due to error code C4: Broken communication with joints. This improvement will affect robot when the software upgrade is installed
- Reduces the appearance of motor encoder index drift errors. The Problem can still be a mechanical issue and therefore not removed by this fix
Safety Control Board
- Fixed issue - violation C191A15 (robot is moving in stop mode) when using "robot not stopped output" and activated safeguard
- SCB (uB): Fixed occasional 'Joint Limit Violation' bug, preventing the robot from always entering recovery mode at start-up if one or more joint position limits are violated
