Technical Support Bulletin

PreciseFlex 400 Rev D robots (manufactured August 2025 and later) and PreciseFlex 3400 Rev D robots (manufactured December 2024 and later) do not automatically recognize Linear Rails manufactured before March 2023. This TSB provides instructions on how to identify the robot to rail incompatibility issue. Provides instructions on how to upgrade the GSB software to resolve the issue.

This Technical Service Bulletin (TSB) addresses potential hardware failure of the front and bottom-facing LED PCBAs or IntelliGuide vision processor of the IntelliGuide v23 and v60 products.

On PreciseFlex 400 and PreciseFlex 3400 robots with hardware revision 9J/9K, it was discovered that the robot arm would descend 25 mm+ on the Z axis if main AC input to the robot is removed while robot high power is enabled. However, if the E-Stop is engaged and then AC power is removed, the arm will remain stable.  TSB-1278 provides instructions for installing a software patch that prevents the link from descending in the event main power is removed while robot high power is enabled.

G6xxxx controls with date codes of 2303 or 2304 were shipped from the supplier with a version of Guidance Programming Language (GPL) loaded on them that is incompatible with the revision of amplifier in the controller. This results in problems when the controller is being initialized. An update to version 5.0H1 GPL remedies the situation.
