5.9 Serial measurement board memorySerial measurement board (SMB)The serial measurement board (SMB) primarily gathers resolver data from therobot’s (or additional axes) motors. This data is used to measure the speed andposition of each axis. Each SMB is capable of measuring up to 7 axes. It also storesa number of data pertaining to each robot.This data is used by the controller and can be transferred between the SMB andthe controller. Normally, the data is transferred automatically, but it can also bedone manually.The SMB data is affected when:• The robot is replaced• The SMB is replaced• The controller (or its flash disk or mass memory unit) is replaced.• Updating with new calibration dataThe following data is stored on the SMB:• Serial number for the mechanical unit• Joint calibration data• SIS data (Service Information System)Note that if the IRC5 controller is to be connected to a robot with an older SMB,not equipped with data storage capability, the SMB must be replaced.SMB data updatethen...If...the data stored in the SMB is automaticallycopied to the controller memory.the flash disk or mass memory or the com-plete controller is new or replaced by an un-used spare part...the data stored in the controller memory isautomatically copied to the robot SMBmemory.the SMB is replaced by a new, unused, sparepart SMB...the data in the controller memory and therobot SMB memory is different. You mustupdate the controller memory manuallyfrom the the robot SMB memory.the flash disk or the complete controller isreplaced by a spare part, previously used inanother system...the data in the controller memory and therobot SMB memory is different. You mustfirst clear the data in the new robot SMBmemory, and then update the robot SMBmemory with the data from the controllermemory.the SMB is replaced by a spare part SMB,previously used in another system...the data in the controller memory and therobot SMB memory is different. You mustupdate the robot SMB memory manuallyfrom the controller memory.new calibration data has been loaded viaRobotStudio or using the FlexPendant andthe system has been restarted...Check that the new calibration values belongto a manipulator with the serial numberdefined in your system.Continues on next pageProduct manual - IRB 360 2513HAC030005-001 Revision: U© Copyright 2008-2018 ABB.
